MainForm.vb update (downloads files from GitHub)

I'm not ready for the rest of this to go yet, but this is one hell of an
update, and I want to commit it to be able to revert back here in the
event of an issue.

This update will dynamically grab the directory from GitHub and strip
out all but the script files folder. This will mean folks will not have
to go into SIR to get scripts, and we can push out updates just by
instructing users to "reclick". Committing now so as not to lose this
work. :)
Removed config folder

Basically, I don't want this mucking up the beta counties who are
choosing to download this work. Plus, this will work better with the new
config program I'm finishing. My repo for the new version is
https://github.com/theVKC/BlueZone-Scripts-Installer, and I encourage
folks to download/mod/update. I can move that repo to the DHS (or
county) groups if it ever comes up. :)
Removed config program

This will now be stored on it's own repo (and delivered direct to
agencies via SIR or possibly email). Removed from repo entirely.
Merge pull request #4 from MN-DHS-BZS-County-Programmers/VKC-multi-location-support

Removed all traces of the config program
