GTalk account changes in Empathy

[Cosimo Cecchi <cosimoc gnome org>]

Hi GNOME doc team,

we just merged a change in Empathy which fixes a regression wrt the
handling of Google Talk accounts.
This implies the following changes:
* having a specialized widget for Google Talk accounts in the first time
wizard, like we do for other protocols.
* a "Google Talk" entry is present in the protocol chooser when the user
wants to add a new account, with the relevant icon.
* the GTalk icon is displayed in the account settings dialog, together
with a proper example label if the account is a Google Talk one, like it
happens for other protocols.

Please reply off-list as well, as I do not get mail for gnome-doc-list.

Thanks,

Cosimo
