Profile Manager [MJ-539]

Can display and exclude certain profileunits as you wish with BaseProfileUnitManager(display, exclude, order*)
Example:
manager = BaseProfileUnitManager(None, ['website'])
units = manager.displayed_units(profileunits)

All profileunits would be displayed but 'website' profileunits on whatever view.

All Tests Pass

* - To be implemented at some point. Made a TODO
