Tweak titles pyplot examples.
In particular, arrange to not capitalize pyplot. The old titles were not particularly great (and likely derived automatically from the filename back when the move to s-g was done). Also merge the pyplot_text and pyplot_mathtext examples (both examples actually show both text and mathtext).
