Hotfix for Zoning Atlas Data

* Because the Zoning Atlas data did not properly display for users who chose to use Excel as their CSV viewer, we are now providing a Sharepoint link that is in XLSX format for their conveinence.
* Even more annoying was that the shapefile did not include any shapes when we exported it. So we also had to create the shapefile manually and put into sharefile.

Related to #366 and #365, but does not fix them beyond Zoning Atlas.
