FUNCTIONS FILE update

I added a line in FUNCTIONS FILE to correct the
worker_county_code_determination function issues when I'm trying to look
at my own work. State folks are county 91, but we have "PW numbers" and
not "x191 numbers". Easy fix.
Second major change to PDTE

It now has buttons for lots more REPT screens, which will fit in nicely
for change #3: REPT generators all over REPT in MAXIS.

For now, I added the REPT/ACTV stats, as well as a piece to get COLA
income types from UNEA for these ACTV cases. COLA's coming, ya-know.

I also updated the PND2 dialog and created two new dialogs for "REPT
scanning". I might use them, I might not. Oh well, it's a branch, after
all. :)
