Unbreak Team hats, shrink some hat sizes

Adjust to reduced ammo menu dimensions.

Fix kamikaze portal loop

Sounds: * Added new sounds: Parachute, bump (e.g. hog falls too far), Drill Rocket * Replaced existing sounds: Baseball bat, Rope

This change allows computers limited to 512 texture size like szczur's card to run Hedgewars, so long as reduce quality is set to eliminate background textures. It makes Ammo menu and Hats multicolumn, 512 high.

Fix wrong sized, wrong colored Splash.png in Art theme

Engine: * Added new script call: OnGearDamage(GearID : integer, Damage : integer) - triggered once gears are damaged * Renamed script call: OnResurrect is now called OnGearResurrect * Added new script functions: CampaignLock(key : string), CampaignUnlock(key : string) - toggles for (not yet implemented) campaign access and progress flags

Engine: * Tiny adjustment to improve AI's Watermelon Bomb accuracy Graphics: * New flame graphics * Fixed mirrored earth in the mirrored fort graphic

Fix swapped x/y in drill rocket test

Untested fix of r3672 - should avoid hogs dying due to multiple health machine sources, and inappropriate application of karma/vampirism to these.

Probably fix missing hats.

Remove ready timer halting game ticks in chat

Trying to adjust behaviour of multishoot w/ portal gun so switching weapons works correctly. Here's hoping I'm checking the hint correctly now.
