no need to use urllib2.install_opener
remove live functionality

The GOM livestream is now implemented using Adobe's HTTP Dynamic
Streaming (HDS). It would be a challenge to get this working in
XBMC (there is no .m3u8 available, only the manifest.f4m).

sjp/GOMstreamer has also thrown in the towel.
Change proxy url format

New format replaces the remoteIP with localhost:PORT, and appends
&remote_ip=??&payload=??. This somewhat simplifies logic especially
concerning parameter double escaping.

Before:
http://localhost:1234?dest=http%3A%2F%2F1.2.3.4%2Fstream.gom%3Fvjoinid%3D.....&payload=...

After:
http://localhost:1234/stream.gom?vjoinid=..&bid=.....&remote_ip=...&payload=...
greatly simplify proxy using asynchat
proxy: use 4 spaces
proxy: 2mb buffer size
Tweaks to login

* Test that login has succeeded by checking SES_userno cookie
* return True or False, rather than LOGIN_*
* If uno is '0' in FlashVars, raise NotLoggedInException
