[evolution-patches] Conduits: Authentication support for TODO conduits

["Veerapuram Varadhan" <vvaradhan novell com>]

Hi,

Attached patches allows tasks-conduits to sync against
Exchange/Groupwise accounts that requires authentication while opening
tasks.

Let me know your comments.

Thanks, 

V. Varadhan
