The icons used for the status bar event icons were recently sorted,
resulting in a reversal of the filled/unfilled pairs. This PR makes
them not rely on the order. This also improves the centering of the
text in the buttons. The complaint about the word "Space" is because
this word has a descender. This requires using BLF_boundbox, rather
than BLF_width_and_height to get the position relative to the baseline.
