Modified the way the history interacts with other components.

* Main class is now responsible for updating map components
  whenever the current map changes (even rewinding): this simplifies
  other objects because they don't have to know anything about how
  the data is being displayed later (no CP/RP juggling everywhere)
* Added undo/reset actions to main view, including menu items
* ProjectionHistory now has specific signals for each change
  happening to the history
