Update to 20160106 OS X Preview for Developers release.

byuu says:

New update. Most of the work today went into eliminating hiro::Image
from all objects in all ports, replacing with nall::image. That took an
eternity.

Changelog:
- fixed crashing bug when loading games [thanks endrift!!]
- toggling "show status bar" option adjusts window geometry (not
  supposed to recenter the window, though)
- button sizes improved; icon-only button icons no longer being cut off
