DEV-44861: Support a home_sidetray_url from login.cgi

The URL for the Home side tray is specified in settings.xml. It can
now be overriden on a grid-level via a "home_sidetray_url" token sent
by login.cgi.

I also updated the Home URL in settings.xml to pass through a bunch of
information to the web server as query params. These include:

p= : the authentication token from login.cgi
lang= : the user's current two-letter language setting
channel= : the viewer's channel name, e.g., "Second Life Beta",
"Second Life Release", "Snowglobe", etc.
version= : the viewer's version number, e.g., "2.0.0.200712"
major= : the viewer's major version number, e.g. "2"
minor= : the viewer's minor version number, e.g. "0"
