fix for various crashes from incorrect poll functions.

- bevel had incorrect cancel when initialization failed which could crash (own mistake).
- main particle poll function didnt check if the area/region were NULL.
- some uv operators needed space image but didnt check for it. also use uv_ prefix for most operator functions.
