Corrected imports of .Net stuff - if python.net interpreter is not present everything still works - but a warning message is displayed.

Package inport/export functionality corrected/improved. Export was rewriten so that it outputs Categories/widgets/Inputs/... always in the same order as well as notifies the user what it is exporting.

subgroup querying widget now returns the complement as well. added widget for constructing tables out of sets.

The only thing person has to do to add package is to add it to mothra/settings/INSTALLED_APPS.
