[evolution-patches] Evolution-iPod Sync EPlugin

Hi,

Just over the weekend i was trying Justin Wakes Evolution-iPod Sync
bounty work, updated that to latest hal apis and made that a eplugin.

This is just a fun work over the weekend. It just works, and of course a
lot more can be done to this in future. Just r-click on the
e-source-list tree, and say Sync to iPod. it works. Strings/errors/etc
needs to be corrected further.

This can work well with 2.4.0 as well. Just need some comments on the
idea. If its ok, we can improve further.
