Quick Explode operator:
* Sets up a particle system and an explode modifier. * In "blend" mode requires two selected objects and creates "crossed keyed" particle systems between the objects for a simple blend effect where the first object explodes and then recombines as the second object. * Also renamed the other quick effect operators as "Quick ..." to bring some consistency to the operators (also nice that now you can just write "quick" to the operator search and get all these operators).
