Enable push to talk on windows and linux.

[GrayHatter]

Linux is a bit complicated to get working. You have to ln -s /dev/input/the_kbd_you_want ~/.config/tox/ptt-kbd as root, then change the ownership of that file to your user, then if you're sane, you'll lock down permissions.

@stal888 maybe you can implement this in OSX as well?

ability to change the button, coming soon?

[stal888]

I have exams to do -- in the meantime, can you implement a stub get_ptt(); in cocoa/main.m so the build doesn't break?

[GrayHatter]

@stal888 done

I'm still working on this one, just need to dive into Xinput as the fallback for linux, I could probably be merged now for windows while I add linux support
