New tacticool icons for bitterfrost grenades, by EvilBob22.

Nicer strat images for higher tier Bitterfrost Grenades.

Fixed an issue where the grenade from Bitterfrost Bomber would not be usable if the soldier was getting launch grenade from the launcher instead of class abilities.
Patched Ice Canister Activate to truely convert damage. better handling for bonus scaling potency should the user decide to make it non-zero.

Added Russian translation by Aks

fixed basic high velocity nozzles granting a larger than intended bonus to ice chemstorm radius.
fixed advanced and superior high velocity nozzles not granting a bonus to ice chemstorm radius.
fixed bitterfrost rounds/etc freeze effect showing up in tactical text unlocalized.

Reworked ammo, ripjack to use an immediate ability trigger instead of an event.
Added a hook to add Bitterfrost to weapons as a bonus effect.

updated with new metallic textures/etc for the cryolator.
recoloured cryolauncher projectile to be more blue instead of red/yellow.
