Refactor statusbar.c
This a preparatory patch. Refactor statusbar.c to compartmentalise the drawing of the statusbar "widgets". We can now begin to see what a generalised widget drawing interface would look like. Note that at the moment we don't gracefully handle situations where "widgets" run out of space. That will come as we generalise from here.
