Fix for bug #366, delete gear if hog is drowning (needed either that or a check on nil Gear^.Hedgehog^.Gear)

Don't remove client's teams from teams list on "ROUNDFINISHED 0", just send team removal message to others. This should fix problems with ghost teams in frontend. Not tested at all, successfully built on first attempt, which is considered as a bad sign :D Server still thinks game proceeds, so restart isn't possible.

oops

android: fix finding cache dir on prefroyo devices, it now creates the Hedgewars folder if it wasn't there

attractiveness tweak to the text clip

Clamp name/team name textures to avoid long team / hog name abuse. Limit width in px instead of chars to avoid unicode issues.

don't use currenthedgehog

use per hog ammo game flag. improves AI play

oops

right-click colour selection to scroll backwards through colours (bit hackish, subclassing + right click handling would be better than custom menu item signal)
