Pull out the behaviour in grab_label and search_start into one utility

function menu_filter(). The plan is to eventually merge in grab_menu too.
Shrinks the code a fair bit.

Also, change XMaskEvent for XWindowEvent to prevent getting exposes for other
windows. This is particuarly noticable on slow machines with a LOT of xterms
(todd, you're an odd man).

ok okan@, todd@.
