Update to 0.7.20:

telepathy-glib 0.7.20 (2008-12-14)
==================================

The "xfs_freeze stole the night" release.

Enhancements:

* Updated to spec version 0.17.16
  - Generate code for the Messages interface, which is now undrafted.

Fixes:

* fd.o #18845: don't throw a critical error from TpConnection if the
  corresponding CM falls off the bus.

* fd.o #18926: avoid using a non-top-level GLib header

telepathy-glib 0.7.19 (2008-12-01)
==================================

The "fast path" release.

Enhancements:

* TpContact now has a fast path using the Contacts interface to reduce
  D-Bus round-trips, if supported

* tp_connection_get_contact_attributes integrates the Contacts interface
  with TpConnection's handle reference tracking at a lower level

* TpChannel now tracks its immutable properties (as provided by
  Requests.NewChannels, Requests.CreateChannel and Requests.EnsureChannel),
  can be constructed from a dictionary of immutable properties
  (tp_channel_new_from_properties), and has a fast path using GetAll to reduce
  round trips (if supported); when constructed from a dictionary of immutable
  properties, non-Group channels should become 'ready' in a single round-trip

* Only use the Properties mixin in there are properties defined

Fixes:

* fd.o #15092: mixins in a superclass should now work correctly in subclasses

* fd.o #18151: tp_base_connection_dispose asserts if there are two connections \ 
to the same account
