Grease Pencil: WIP Code Reordering + Context Stuff

* Shuffled some code around, and renamed some functions used for getting context info
- Split UI-buttons into a separate file from stroke-drawing code
- Removed some obsolete code (i.e. old paint code that used to be in _edit, but which has been moved to _paint). 

* Made drawing in 3D-View default to using the active object as the owner of the Grease Pencil data. For now, the drawing code will therefore only show the GP data for the active object only. More work to come on this.

* Fixed freeing code for Objects/Scenes with GP data.
