Cleaned up main form

* Removed old functions.
* Fixed bug with PAD download (it was set to `= true` when that wasn't
necessary).
* Added lots of comments.
* List of scripts now looks at different URLs depending on
whether-or-not agency is beta.
* Got rid of another issue involving the custom file paths and that `=
true` business.

Tested, and it works. Sending to other counties now.
