[Bug]: macosx backend pause() cannot be ctrl-c'd

[anntzer]

Bug summary

Unlike with other backends, a plt.pause() on a macosx figure cannot be interrupted with ctrl-c.

Code for reproduction

python -c 'from pylab import *; plot(); show(block=False); pause(5)'

Then press ctrl-c while the pause is running.

Actual outcome

pause() is not interrupted.

Expected outcome

pause is interrupted, like for other backends.

Additional information

Likely the solution is the same as for qt: the ctrl-c handling code in FigureManagerMac.start_main_loop (i.e. _maybe_allow_interrupt, for the qt case) needs to be more or less duplicated into FigureCanvasMac.start_event_loop -- (except that right now FigureCanvasMac.start_event_loop is implemented in ObjC so things need to be moved around a bit).
