Subject: [PATCH] Stop a view that was not loaded from being loaded while being
 removed.

Example: If GitX started in stage view and the window was closed without ever looking at the history view, then [self view] will cause the history view's nib to be loaded which kicks off loading in the rev list. Wastes a lot of CPU cycles for no reason.
