Also removes the return value from the BITMAP_STORE's themeChanged
method as it will provide the wrong answer for the second frame it's
called on.
Also hooked up ACTION_TOOLBAR, the app launcher, and the project tree
to the wx event for system color changes so they change on the fly.

Before, it was possible for the canvas to steal the
focus if the cursor was only moved over it and not
clicked. Now, the canvas will only take the focus if
the frame is active.

* Implement ReparentQuasiModal for OSX natively
* Implement ForceFocus of OSX natively
This change means we no longer rely on the kicad-specific functions in our osx wx fork.
