Switched magic zoom to point to ZoomLocations feature class instead of Municipalities.

Helps out with #10.
Merge branch 'master' of https://github.com/agrc/Broadband.Editing into magic-zoom-enhancements

* 'master' of https://github.com/agrc/Broadband.Editing:
  Undo/Redo basic functionality.
  Updating agrc submodule to get magic zoom updates.
  Added separate `osx` and `windows` properties to the `AGRC Build` system.
  This is just more for me to remember fork and pull stuff.
Update to latest agrc amd branch.

I believe that this is the last piece to closing #10.
Merge pull request #11 from stdavis/magic-zoom-enhancements
