Fixed bug where arrows would get stuck in midair after hitting func_breakable_surf

Added support for NextBot damage and pinning
Redid impact effect code so it derives from surface properties instead of the material type
Added ignite to explosion arrow so vFire can take advantage of it
Fixed bug where arrows would occasionally get stuck in midair after hitting NPCs

Added Spawn Icon (wow!)

Arrows now stick into npcs and players and follow them around, including grapple arrows. They are removed upon the death of the npc or player

Explosive arrow now uses util.BlastDamageInfo, so it properly emits burn damage instead of blast type damage.

Damage was adjusted across the board so it scales better with the charging (as a side effect the explosive bolt is overpowered as sin now).

Uncharged arrows now no longer ignite props, mimicking the old behavior pre-2018.

The glow effect on the arrow now scales with the charge.

The impact effect scales with the charge properly (this was broken before, oops).

The impact effects based on what surface you hit work properly now and have additional ones for hitting alien flesh, wood, and grass.

Rewrote pin code to fix every stupid last bug with it, velocity is now constant instead of based on charge, NPCs can now be pinned to props, trace is a hull trace instead of a line trace which heavily improves hit accuracy and hit chance; this thing is potentially one of the most overpowered weapons you can use now.
