Soc Proofing

Added some Soc-Proofing (TM) to BCMS. I made that she'll be forced to select a Bank whenever she changes the O.R.# manually. In turn, the date and O.R.#'s are blanked whenever she changes Bank.

I met a lot of resistance from her. In due time, I hope she somes to realize that it's doing all of us a favor.
