Spoke too soon on the NAV scripts, going into their own folder

Basically, the Power Pad can't seem to find them if they aren't in the
same folder as the Power Pad. Oh well. Moved them back to the default
folder.
Added Global Variables file

This will load the custom variables for each agency.
Added first redirect, for BULK scripts

Needs work, as it doesn't have them all there. This is just a copy of
the PDTE script (which will be retired because of this).
