* XMPP
o Less likely to send messages to a contact's idle/inactive resource. Previously, if a message was received from a specific resource, responses would be sent to that resource until either it went offline or a message is received from another resource. Now, messages are sent to the bare JID upon receipt of any presence change from the contact.
o Added support for the SCRAM-SHA-1 SASL mechanism. This is only available when built without Cyrus SASL support.
o When getting info on a domain-only (server) JID, show uptime (when given by the result of the "last query") and don't show status as offline.
o Fix getting info on your own JID.
o Wrap XHTML messages in <p>, as described in XEP-0071, for compatibility with some clients.
o Don't do an SRV lookup for a STUN server associated with the account if one is already set globally in prefs.
o Don't send custom smileys larger than the recommended maximum object size specified in the BoB XEP. This prevents a client from being disconnected by servers that dislike overly-large stanzas.
o Fix receiving messages without markup over an Openfire BOSH connection (forcibly put the stanzas in the jabber:client namespace).
o The default value for the file transfer proxies is automatically updated when an account connects, if it is still the old (broken) default (from 'proxy.jabber.org' to 'proxy.eu.jabber.org').
o Fix an issue where libpurple created duplicate buddies if the roster contains a buddy in two groups that differ only by case (e.g. "XMPP" and "xmpp") (or not at all).
