Hello Thomas!

I recently extended our test data to fully cover all chat extensions
possible used by [Sync]Evolution and found that the new ones, in
contrast to those that we discussed a while back, are not stored on the
server. Perhaps you can add them?

X-GADUGADU
X-JABBER
X-MSN
X-SIP
X-SKYPE
X-GROUPWISE

In the meantime I'll ignore the data loss in synccompare, to keep the
tests passing.
