Creating New Land Management Areas and Geometry in Django

[kkemp85]

As outlined by @mradamcox, we need a way for me to create new land management areas on my own to make the process easier for everyone. I can do everything but add in new geometry/boundary shapefiles. He will set up a way for me to add in the geometry by linking to QGIS. This will be integral to adding in missing LMUs from State agencies and creating new local and federal level accounts.

Central to this is going to be a new receiver on the ManagementArea model that is triggered via the post_save signal (or something like that) and will push the saved management area's id to any overlapping geometries.
