[Deskbar] Preferences UI

[Raphaël Slinckx <raphael slinckx net>]

Hi !

I lost the preferences UI mail so i start a new thread, sorry.

Can you explain what is the handler.recheck_requirements(self) for ?

If i understand correctly, it's for the case when the handler is not
happy anymore but was in the past, is that right ?

In that case, i would prefer to simply unload the module that is not
happy anymore, and not sprinkle the code with "if self.i_am_valid"
