[Mono-aspnet-list] Ubuntu, mod_mono, and 2.6

After some more editing, I've got some answers just in case anyone
else needs to upgrade too.

The multiple servers running was caused by me having multiple
virtualhosts, and setting MonoServerPath in them.

Editing /etc/mono-server2/mono-server2-hosts.conf:
MonoServerPath default /opt/mono2.6/bin/mod-mono-server2
MonoPath default /opt/mono2.6/lib

The "default" above looks to be the name of the .webapp, but I changed
mine to a different name, and it still works.

Everything auto starts now, and uses the correct assemblies. I
couldn't prepend the new lib path to the existing MonoPath, it still
attempted to load the wrong mscorlib, and then crashed.
