Changed my previous implementation to an ifdef at Henrik's request. Disable touch controls for "desktop" platforms(Windows/Linux/mac). The intention was to disable the invisible controls, but this commit will break the touch controls completely, even if visible. Platforms such as Android/Meego shouldn't be affected.
Fix ifdefs not to break iOS.
No need to have an if true there.
Merge pull request #2257 from thedax/disableTouchOnDesktop
