Instead of creating a pango layout all the time (e.g. twice per redraw), we now
only create a single layout which we keep around all the time and update as
needed. Hopefully this helps a little.

This makes the textbox pass the markup/text it is given to oopango immediately.
If it is invalid, a lua error will be thrown and the old text will still be
shown.
This fixes a bug where the whole wibox isn't redrawn when a textbox complains
about broken UTF8.

This makes sure that textbox.text = "foo" doesn't work at all. It was never
supposed to work anyway. Sorry that I break stuff again.
