Title: Loop selection and SingleLayerOnionSkin enabled

Added a loop start and end control. (needs a little cleaning but works fine)

added the possibility to toggle from multiple layer onionskin to single layer onionskin (only shows onionskin from active layer).

also has a few line for new onionskin color control enhancement ( commented for the moment ).
