Plugins Atom Mover

- Removed scene dependencies.
- Framerate indipendent continuous translation and rotation (should be there from the beginning ).
- Added reset rotations button. With absolute rotations I was trying to do something senseless. If you want to set an absolute rotation, just reset rotations an set the rotations you want (Qaternion demon tried to confuse me but... after a long fight... I win! ).
- Code optimization.

The plugin now have all the features I planned so I will call it "Version 1.0". This doesn't mean I will not update it if I find other usefull features.

- First implementation of set absolute rotations (doesn't really works. use it only to reset rotations to 0,0,0. Still WIP, needs tests).
- Fixed local translation increments ratio.
- Code optimization.
