Starting to integrate fixture remap code

Need to fix minor graphics aspects and the actual project remapping
Fixed connection graph painting
Remap: fixtures replacement done, scene values remapping done
Added remap fixture removal + fixed remap fixtures add

Fixed mouse wheel scroll on fixtures remap dialog
Added Chaser remap (in sequence mode)

Allow multiple remap (one to many). Slow down a bit but it's freaking awesome !
Added progress popup dialog
Added EFX remapping code. The solution is not optimized but at the moment I haven't found anything better
Finally enabled fixture remapping functionality.

TODO:
- fix fixture groups (especially for RGB matrices)
- review all VC widgets associations
Added VC sliders channels remapping
Improved functions name with ID for consistency

Updated translations
