[evolution-patches] Calendar E-Plugin hook hack

[Praveen Kumar <kpraveen novell com>]

Hi -

The target that was provided by the Calendar Configuration E-Plugin hook
didn't carry enough information for the plugin to distinguish between
"Calendar" and "Tasks" components. Exchange connector needs it for
populating the different hierarchies in the "New Calendar"/"New Tasks"
dialog as a part of supporting calendar and tasks hierarchies. So, there
was a hack needed to pass this and other needed information to the
plugin. I am attaching the patch. Please review it.

PS: 'diff' ran from 'evolution/calendar' directory.

Thanks -
Praveen.
