beamerthemeUMBC.sty: allow partless sections.
Sometimes having a full Part : Section hierarchy is too much. We can
now use only sections, and the part titles (and the colon separators)
will be gracefully omitted.

beamerinnerthemeUMBC.sty: no line break after "Proof."
There's no automatic line break after "Theorem.", "Lemmas.", etc.,
these days, but there is still one (with the wrong spacing!) after
"Proof." Here we override the beamer template to make "Proof." work
like the others.
