adding files for deb packaging.
Refactoring

Added function to get the child space object to Spaces.  Updated display of
child spaces to use verbose names (instead of column names).
Spaces can be edited

refs #6008

Added a view for editing spaces.  Access protocol is not editable once a
space has been created, enforced at the template and form clean level.
Enable deleting locations

refs #6008

Added view to delete locations if there are no foreign keys pointing at
them.  Used a decorator on the delete function to require confirmation
before deleting, and enforce only deleting if there are no dependent
objects.
Allowed deletion of Spaces and Pipelines

refs #6008

Added delete views for Spaces and Pipelines.  Updated the dependent_objects
function to work with OneToOneFields (ignore them, since they're deleted
when the parent object is).  Factored out the common code in getting a
delete_context.  Added links to the delete pages to the templates.
