Duracloud: Space path is optional

refs #7133
Duracloud: Browse works without leading /

refs #7133

Browse resources should only join with the Space/Location path if it does
not contain the Space/Location path already.  Some calls to browse contain
the full path, and others relative paths.  This should work for Spaces with
or without a leading / in the path.

Update directory browser JS in SS to handle paths that don't begin with / as
well.
Duracloud: Minor fixes

Don't display password, show the space path as <None> if it doesn't
exist.
Logging: Configure

refs #6812

Configure Django's logging and change references from logging root module
(logging.foo) to the fetched logger. Disable South having logging at
DEBUG.
