Henek adds a flamethrower, updates some translations, and tweaks how fire works.

Engine: * Modified gas grenade and added graphics to it (better get a nose clip!) * Added the ability to tint visual gears * Added the ability to tint explosion effects * Birdy's eggs now cause a small green explosion

Skip collision on X for barrels that aren't knocked over

Increase minimum threshold for barrel damage to reduce likelihood of blowing one up on jumping out, increase damage to compensate (may need tweaking). Only apply dX for collision w/ kick if barrel is rolling.

portal-link-bugfix: make sure deleted portals don't reset links other than those to themselves

remove all portal specific code from EndTurnCleanup(), instead have portals self destruct if "CurrentHedgehog" is not the portal's creator

Change to just set timer to 0

Fix for artillery mode weapon use

* make portals delete each other only indirectly (by setting timer to 0) * add VGSHandler.inc to CMakeLists.txt
