Connect to remote Xapian database

[aarcro]

I patched the 1.1.5 backend to connect to a remote Xapian when a (host, port) tuple is used for HAYSTACK_XAPIAN_PATH

You can see it here:

No clue how to use git, so I guess it added as a new branch. I really just wanted a new head off the 1.1.5 tag, but maybe that's more of an HG kind of thing?

This is a nice addition to Xapian-Haystack. It will require some tests to ensure it is working, and I believe we could use the same notation as Django uses for connections (i.e. PATH and PORT as optional arguments of connections).
