Snes9x 1.61 released

[Montie2k]

This is a small release for a bunch of little things that have accumulated. Big changes behind the hood are a change to the tile renderer so that it builds much quicker, and a swap of the Gtk port to C++ bindings, both of which should be unnoticeable. Michael Buckley also wrote a completely new macOS port, due to the complete deprecation of the classic APIs the old port used.
