[resend]winecfg fixes, with Mike Hearn's suggestions

[Crestez Leonard]

This patch makes a bunch of small winecfg fixes. Since most of them are
just a few lines in length I don't think it's worth splitting them.

I also implemented Mike Hearn's suggestions.
This was sent about a week ago.

Changelog:
	fix add application (memory error)
	fix apply button lighting up in audio tab
	fix video tab(crash when checking desktop, apply button not lighting up
	deal with invalid Desktop registry value in video tab
	fix apply button in libraries tab
	cleaned up and documented all the conversions in the libraries tab.
