Linux + OS X support, compatibility fixes!

We've just released an update that we decided to call v1.16. It adds and contains, amongst other boring techy things:

• Linux support!

• OSX support!

• SDL2 as platform abstraction library instead of OpenTK, fixes multiple compatibility issues

• GPU-scaled fullscreen mode, the game never changes screen resolution anymore

• Updated FMOD audio library to version 4.44.30, fixes audio related crashes

• The game doesn't use XML serializers anymore, fixes an extremely rare crash issue

• Improved debug logging

• Made gamepad support more robust

• Got rid of GLU requirement

• Multiple minor compatibility fixes

Linux and OS X versions will be available for download also for people who bought the game before the update!
