Revert to *.XXcol.* being an exact column width, add *.cXX.* support
That previous commit made all *.40col.msg files display for 80 column users. Not my intention. So revert to the previous behavior of *.XXcol.* display files. I didn't want to go renaming a bunch of menu files as a result of the previous commit and I didn't want a bunch of sysops with *.XXcol.* files to be suddenly surprised at their new BBS behavior. And introduce a new file naming convention, *.cXX.* (where XX is a MINIMUM column width). This is the same naming convention used by Mystic, which also treats it is as a minimum terminal width, not a required exact width.
