Fixed black screen yawn effect not happening when player is tired unless the player slept first

Fixed sleep meter updating incorrectly whenever nearby player's tiredness level sync'd to clients.

*Actually* fixed sleep meter not updating upon login until the player slept first.

Fixed sleep meter not updating until player lies down

- Added compatibility for my Immersive Login mod (player logs in lying down with eyes closed)

- Added "AttenuateSound" config option (set to zero to disable sound attenuation while sleeping)
- Added 20-30 second delay before sound attenuation kicks in to simulate falling asleep
- Improved compatibility with Medical Attention mod (obviously turn MA sleep mode off as it conflicts)
- Other minor fixes I've forgotten, and began work on new and much improved version 2 of this mod :)

- Improved compatibility for mods like Boomlay's sleeping mod which has a sleeping action attached to beds.
- Added sound attenuation to sleeping players - for now it is basically a flashbang effect, but as an audio engineering nerd I plan to significantly improve this in the future.

PS. I have become much more experienced at modding since creating this re-make while learning the ropes. The code here is "acceptable", but not optimal. By that, I mean it works, but it's like a functioning alcoholic. I plan to remake this mod from the ground-up when I have time - but for now, it is what it is, and if you're like me and love immersion - it works!

Stay tuned for "ZenSleep v2.0". I've already spent so much time on this mod my girlfriend wants to leave me, but I'm no quitter. Maybe late Q1/Q2 of 2023 I'll have a radical improvement for those who really like this mod. I may also be single by then, so if you're a hot DayZ gamer lady from Australia, hit me up

Fixed "OnlyShowSleepAbovePercent" setting not working properly, and this setting can now be used in conjunction with "OnlyShowSleepOnInventory"

So for example, you can set OnlyShowSleepOnInventory=1 to only display the tiredness meter when the user opens their inventory or lies down to sleep, and set OnlyShowSleepAbovePercent=60 to also show the tiredness meter when the player is 60% tired or more (ie. the sleep energy bar is in the lower 40% and the player is nearing the yawning stage).

This is just for those server owners who want to tidy up the player HUD a little bit since the player doesn't really need to know how tired they are all the time :)

For those with customized versions of this mod who may have modified my original code, the only changes I made are to a few lines of code in the file IngameHud.c

- Added new check for action-based sleeping in addition to gesture-based sleeping (now works with BoomLay's Things modded beds for example)
- Changed the immune system boost to only apply if the player has slept for at least 30 seconds, and is near a fire
- Changed config filename back to ZenSleep.json with a better config update mechanism for the future
- Converted all IsServer() calls to IsDedicatedServer() to optimize performance (only very slightly but hey, why not)

- Changed config file to "ZenSleep_v2.json" so your old config settings don't get over-written - transfer old config to the new config.
- Added option to give the player an immunity boost if they achieve a certain rest threshold (100% by default).
- Added option to recover health & blood faster when sleeping for longer than 30 seconds (set to 0 to disable).
- Changed how the player becomes tired over time based on certain physical activities they're doing:

EnableMovementPenalties=1: Set to 0 to disable movement penalties (this will make the player tired over time without being influenced by activities)
SprintUprightPenalty=1.2x: Player gets tired 20% faster when sprinting upright.
SprintCrouchedPenalty=1.15x: Player gets tired 15% faster when sprinting while crouched.
JoggingPenalty=1.10x: Player gets tired 10% faster while jogging.
ClimbSlowPenalty=1.5x: Player gets tired 50% faster while climbing ladders slowly.
ClimbFastPenalty=2x: Player gets tired 100% faster while climbing ladders quickly.
SwimSlowPenalty=1.5x: Player gets tired 50% faster while swimming slowly.
SwimFastPenalty=2x: Player gets tired 100% faster while swimming quickly.
WalkingHeavyItemPenalty=2x: Player gets tired 100% faster while carrying heavy objects (sheet metal, logs, basebuilding/storage items etc).

As always the latest source code is available on my github at www.zenarchist.io to do with as you please :) enjoy!
