• Fixed error when using colorable particles on proxyent_tf2critglow

As you cower in fear from the sixteenth year straight of terrifying Scream Fortress updates, you might think you're safe taking refuge in another old game. "The Halloween updates can't get me here in Garry's Mod," you say to yourself. "Surely nothing scary could happen in a hat painting addon from 2013!" But you would be WRONG! [sound of your own skeleton crapping itself in fear] For the Hat Painter tool... now has Halloween spell paints, in all their garish, hue-shifting glory! Pain-stakingly recreated one-to-one from TF2, it's like you never even left Scream Fortress.

Experience the unspeakable terror of painting hats with one of three imperceptibly different shades of nauseating greenish-yellow, a glowing, fluorescent purple, or even that team-colored one! Spiral into crippling existential dread as you contemplate spending unfathomable amounts of money to acquire these color-changing hats for yourself in this dead-end economy! Will you buy a full loadout of flashing red-orange cosmetics to call your very own, or will you pay your rent? The decision will haunt you for the rest of your days! [sound of going into inescapable debt]

But that's not all! In addition to the six horrifying colors you may already be familiar with, this update includes a seventh, scrapped spell color not witnessed by human eyes in at least twelve years! Excavated from the depths of the TF2 source code under the corpses of long-forgotten developers, this forsaken color is not quite bright orange, not quite cyan, and not quite dark purple. It's like The Color Out of Space, only instead of history's most fearful man not understanding radiation or something, it's a paint you can put on a hat! Don't tell those Workshop commenters that Valve was genuinely considering adding this back in 2012, or they'll have to build a second insane asylum inside the one they're already living in! [sound of a joke being run into the ground]

Happy Halloween, everyone! Enjoy the update, and I hope you all what's that on top of the coat rack!? Oh, it's just a hat painted a nice, tasteful shade of burgundy oh no wait that's your OWN BLOOD

• Added the 2012 Halloween Spell color-changing paints, ported from the TF2 code. Also includes an extra unused spell color!
  
  
• Ported over lots of minor code cleanup from the killstreak eyes tool
  
• Removed redundant nwvars for "TargetEnt" and "PaintVector", instead just use Get/SetParent and Get/SetColor which the game has to network anyway

• Fixed typo in model path
  
• Attempted fix for proxy ents drawing a shadow

• Fixed proxy ents being affected by addons that look for error models by giving them a valid model (melon)
  
• Attempted fix for proxy ents being visible to some players (even though they have both RENDERGROUP_NONE and SetNoDraw) by giving them a blank draw function

• Fixed errors caused by dupes using GenericDuplicatorFunction still having the original entity's Proxyent_TF2CritGlow/ItemPaint value saved into their table

• Fixed errors caused when an entity's Proxyent_TF2CritGlow/ItemPaint value existed but wasn't a valid entity

• The Crit Glow tool can now create Jarate effects
  • The color effect now works on TF2 characters and cosmetics by using the YellowLevel (Jarate) proxy when ModelGlowColor isn't available. The critglow and jarate color effects look exactly the same, so you can also add critglow to characters or put jarate on weapons.
    
  • Added jarate colors (yes, they're different between teams!)
    • Jarated, RED: 6 9 2
      
    • Jarated, BLU: 7 5 1
  • Added jarate drips option
    
  • Added colorable drips option and some custom colors to demonstrate them
    
  • Known issue: a few cosmetic models (models/player/items/spy/pn2_mask.mdl, models/player/items/all_class/saxton_hat_demo.mdl, models/workshop/player/items/pyro/threea_nabler/threea_nabler.mdl) have materials that glitch out when applying the jarate color, but this is a problem with the .vmt files and also occurs in TF2
  
  
• Updated critglow colors to what I'm pretty certain are the exact RGB values (old values were eyeballed and not 100% accurate)
  • Critboost, RED: 80 8 5 (was 94 8 5)
    
  • Critboost, BLU: 5 20 80 (was 6 21 80)
    
  • Mini-crits, RED: 226 150 62 (was 237 140 55)
    
  • Mini-crits, BLU: 29 202 135 (was 28 168 112)
    
  • Hype mode: 50 2 48 (was 50 2 50)
  
  
• Implemented right-click copy feature from the color/material tool, and moved remove to the reload key
  
• Removed "Bone Merger Compatibility Mode" option. This feature only existed to get around a bug with the old Bone Merger tool that's been fixed for years now, and it caused a lot more problems than it solved. The prop_replacementeffect entity still exists so as to not break old saves and dupes.
  
• Redirected paint colors below 3 3 3 (which don't work) to that value so that painting things pure black works more intuitively
  
• Fixed the selected paint category in the controlpanel not updating if the toolgun wasn't the active weapon
  
  
• Major code cleanup and behind-the-scenes code improvements

• Added a new option for custom-colored spark particles that match your selected color
  
• Added preset menus that you can use to save custom colors
  
• Fixed crit sparks not being applied in multiplayer
  
  
• Made the tools look nicer by adding in ControlHelps and TOOL.Information
  
• Colors can now be removed with right click, just like the standard color tool (reload still works)
  
• Reworked the internal code of the paint tool to fix the jittering when changing between categories
  
• Replaced crit spark sliders with checkboxes

• Fixed critboost particles not being precached because a TF2 update moved them into a different .pcf file

• Fixed the paint tool not remembering your selected category when you first start up a game
