Start reorganizing Bin. May break things.

Most salient changes:
- Effect logic is being mostly deprecated. It now uses the effectstackmodel
- Direct access to profiles are being removed. They should be accessed through pCore
- Producers are wrapped in shared_ptr
- The coupling with the Monitor is being reduced. Ideally, there should only be a
signal telling which Producer to display.
- The bin hierarchy is melted into the abstractTreeModel framework. Fusion is done but
there are still duplicate logic
- ProjectClip now inherits ClipController
