optimizations to new ammomenu and overlay

less warning, no rotation glitch, more comments

Resurrector weapon: do not make it end turn, add description, add doStepHedgehogMoving while resurrecting

Rope optimisation. Remove a space in sdl keys that seems like a bug - issue #70

i fix up the new ammo menu finally

(none)

minor stuff

set CurAmmoType to a temp var so I don't have to worry about it switching inside the routine so that I can actually put OnUsedAmmo where it belongs.

Ok. Let's disable the right one this time. In fact, let's just remove newgrave entirely - no point in half-measures.

Disable newgrave - conflicts with resurrection

Extend the >0 / amNothing check

merge

Call OnUsedAmmo *after* doing the normal CurAmmoType stuff so CurAmmoType actually points to the right bloody weapon

Add dummy amResurrector sprite
