Demo V20130529 is now available

This update includes bug-fixes and a little improvement on the mouse interface to work more like you'd expect it to be.
Fixed:
- Pause now works correctly on computers that don't have a joystick plugged in
- Low quality main menu now loads correctly
Also:
- Added Credits
- Changed some GUI elements
- Added command-line parameter "--nojoy" to completely disable joystick support should you still have problems with controls, or simply don't wish to enable it
