Subject: [PATCH] Implement our own navigation out of a grid.

While wxWidgets has Navigate() and NavigateIn(), they're not compiled
on GTK because it supposedly has native TAB control.  Of course its
native TAB control won't get you out of a grid, so that leaves us in
a bit of a pinch.  This implements a poor-man's Navigate() which will
at least get us out of the grid.
