Merge pull request #190 from n8fr8/v11-UI-updates

V11 Google Auth and ui updates
adds display of resource from xmpp data
updated version
fixes Google OAuth2 support to re-up key on login

previously only requested/stored oauth2 key on account setup, which was wrong.
now the XMPPConnection requests a new key each time upon login, transparently to the user.
the only password stored is the x-google-token string in the account password field
which indicates that the GTalkOauth2 SASL auth should be used.
all GTalkOAuth2 code has been centralized in GTalkOAuth2.java class.
