[macOS] Controller support

[frarees]

I play the game via PS3 controller, and sometimes via keyboard. It works great.

But I also have some other controllers available and I'd like to use them for local co-op gameplay:

• OUYA controller
• Steelseries Stratus XL

For the OUYA controller, the game reports buttons being pressed (a green debug info pops up) but the game doesn't actually bind them.

For the Steelseries Stratus XL, only the axis and the central button do work.

I'm testing with v54 on macOS Sierra.

I'm available to offer more in-depth debug with those controllers, feel free to get in touch.

EDIT: also, worth mentioning, the computer can get to sleep on my laptop if using a controller (like when it's actually idle). It seems it is not sending a valid/proper "input event" to the OS?

similar issue for me on OSX. I have an 8bitdo SF30. I set it to Mac mode and works in other games. This game the left stick acts as a mouse but none of the buttons work. The game does detect it, but I cannot set anything.
