Changes to quick explode

Browse Source 
- fix python error when the object had an empty material slot
- initialize start frame from the current frame
- set frame range to 300000 max (which is blenders own maximum)
- mesh order was arbitrary, instead use selected -> active, removed invert option.

also fix for missing include in bpy_extras.view3d_utils
