* Moved Apply button into controls box (resolution, etc.), so its meaning is more obvious.
* Revert now resets the whole screen settings for all workspaces to the configuration at the start of the preflet.
* In confirmation window, renamed Revert to Undo because that's what it actually does (it has nothing to do with the Revert in the main dialog).
* Disabled Defaults button (for now) since it doesn't use the screen's preferred settings and added a few TODOs.
* This should fix bug #321.
Note: Unfortunately, it won't work correctly on R5 because BScreen can only access the active workspace, it seems (locally, I used activate_workspace() for testing the preflet). Also, Haiku doesn't yet support setting screen preferences for each workspace individually, so I couldn't test it.
I hope my code isn't too terrible. :)
