v2.0.1_RC#6

Fixes:

- fixed all remaining upgrade trees for new weapons:

* 'not available' icons
* tool restrictions

- disabled helmet upgrades for exoskeleton

- disabled all props spawned via dynamic_spawn on both maps (suspected
to cause save corruption)

- made all Armory Mod NPC meshes use old and proven meshes - renamed the
old ones to replace the new ones (new ones are suspected to cause save
corruption)

- restored old Radio Mod so that there is musci in bases despite
disabling of dynamicall spawned props

- fixed crashes related to VSK94 wrong anim assigment

Gameplay & balance

- fully implemented KSVK sniper rifle and added it and its ammo to
highest-tier trader stocks

- reduced anti-bleeding upgrades for all armor upgrades 4x and replaced
health-regenerating upgrades with anti-bleeding ones

- reduced anti-damage effectivity of 'kevlar plates', 'steel plates' and
all mutant skins 4x

- reduced anti-damage effectivity of artifacts 2x. So artifacts are now
2x more effective in comparison to above-mentioned attachements
(modified descriptions accordingly)

- changed all anti-damage upgrades of suits to display the property with
positive values instead of negative one

- silencers now increase accuracy by 15% instead of lowering it by 40%
as it was before
