David Capello 02324f4cbb Refactor: move current frame/layer from Sprite class to Editor/DocumentView
This change is the first step to create a mini editor with the capability
to show the animation while we edit other frames. Also it will allow us
to have two or more editors of the same document in different frames.

- Added DocumentLocation: now the location in a document is a property
  of the current Context (Context::getActiveLocation()).
- Added ContextAccess/Reader/Writer classes.
- Added DocumentApi class: high-level API with the majority of methods
  in UndoTransaction class (that were not directly related to a undo
  transaction).
- Added AddFrame/RemoveFrame undoers to handle add/remove frame correctly:
  this fix issue #212.
- Removed SetCurrentLayer/Frame undoers.
