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.
