Babbler Version 0.7.3 released

I've released version 0.7.3 of the Java XMPP library. This is primarily a "bug fix and improvements" release and is compatible with previous 0.7.x releases. Here's the changelog:

• Use single equals sign (“=”) for zero-length data in SASL, as per RFC 6120 § 6.4.2
• Allow configuring a custom stream host and skip proxy discovery then for SI file transfer.
• Implement WebSocket pings/pongs.
• Fix WebSocket’s proxy URI construction.
• Use connect timeout for WebSocket connections.
• XEP-0198: Send an ack right before gracefully closing the stream (i.e. update to version 1.5.2).
• MUC Room “enter” events should fire for oneself entering the room as well.
• Use java.text.Collator for String-based default comparison.
• XEP-0066: Use URI instead of URL.
• Fix XMPP Ping in External Components, which broke the connection.
• Jid.asBareJid returns this if it is already bare, reducing GC pressure.
• connect() method should not throw CancellationException
• Check if the connection has been secured (if configured) before starting to authenticate.
