Subject: [PATCH] change behaviour of menuitemtextinput

Now, if the last line of a menu is a text input item, pressing enter in
that line will not only execute the assigned command, but also close the
menu.

With this, menus without the annoying "[OK]"-button can be created.

Also: emptied text input fields don't magically fill up again, when you
deselect them.
