Use the XGrabKeyboard hack in for alt-tabbing as well. This stops the

mru getting the order messed up when gvim/xpdf et all steal key events.

While i'm here, change the logic in client_cyclenext() to use break instead
of goto, it's nicer that way.

Thirdly, instead of two different kbfuncs, just use the one and a flag.
