keysync: fix bug when no -i or no -o options are specified
keysync: use OrderedDict from ordereddict if on python < 2.7

OrderedDict was included in Python starting with 2.7 as part of the
'collections' module.  The standalone module 'ordereddict' provides a
compatible version for Python < 2.7
run-tests: add test suite that runs ./keysync with a single app as -i or -o

This makes sure the args and defaults are working properly.
jitsi: represent Google Talk as prpl-jabber for now

keysync will have to track the XMPP variants like Google Talk and Facebook
because some apps do special things based on which XMPP variant. For now,
keysync will just mark Google Talk keys as prpl-jabber.
jitsi: fix bug where it was writing data to the wrong key

If the *publicKey_verified line for a given account name came first, then
a key[] would be created there, but then it wouldn't be used in the section
that parsed out the _publicKey line.  I also normalized the code in
*publicKey_verified to be like the other sections.  Hopefully that makes
the code more readable.
