Check for gstHHDriven instead of damage check, so ballgun stops when turn ends in multiattack mode

merge

ignore keymodifers other than ctrl/alt/shift

removed some writelns

first attempt at implementing support for keys with modifiers to use it, the keybinding have to be of the form mod:<modkey>:..:<modkey> <function> <keycode> for instance in an ini file change findhh=h to findhh=mod:lshift h

Make it AI survival almost definitely impossible by adding a 3rd pass to FindGear. 1st pass normal, 2nd pass allow close to objects, 3rd pass, allow overlapping objects.

Not needed here

Removed leftover FFP code: We should now be GL2 GLSL1.30+ forward compatible. Added a seperate shader for the gradient used for water drawing. Disabled 3D mode for GL2 codepath as this still has some FFP left.

- Allow camera movement while current hedgehog is falling - Some tiny changes

Merge

Android: first attempt at using the density call from java

only reset those keys which actually change their bindings

tidy flags

Small improvements to the frontend lib for better debugging

Welp. We have a bit of a problem here. Reverting the move of nextturn. But this causes a desync in scripting unless we can find a better fix.
