Subject: Replace txt_widget_t#selectable with a callback function to query
 whether the widget is selectable. This stops the table code from selecting
 things that aren't really selectable - eg. empty tables, scrollpanes
 containing unselectable widgets, etc. Fixes a bug with the warp menu (thanks
 Proteh).
