Merge lp:~statik/desktopcouch/server-problems into lp:desktopcouch

[Elliot Murphy]

    Don't trigger the desktopcouch path searching and automatic couch startup
    behavior when desktopcouch is imported, this module is used in server
    environments also and thats not very friendly for servers.

    Also: never, ever call sys.exit() during module import. raise an
    ImportError instead so that it's possible to debug.

Fixes some major problems with using the desktopcouch module in server environments.
