Create the PurpleAccountManager API

This replaces most of the purple_accounts_ API, but not quite everything. The
functions that have been replaced have been marked as deprecated and libpurple
has been updated to use the new API.

Testing Done:
* Connected an XMPP account
* Verified chat and ims worked
* Verified that the saved statuses window didn't crash
* Ran the new unit tests.
