[Evolution-hackers] Evolution.Importer.createControl

		void createControl (out Bonobo::Control control);

Shouldn't this just return the value for api consistency?

Passing around pointers to stuff is ugly as hell in c.

And if we're going to change the interfaces anyway, can we ditch the
horribly awful to implement processItem rubbish, and just have loadFile
be synchronous, please?
