LoadBmrbStats Last updated format

The LoadBmrbStats script could recommend people to try downloading statsel_prot.txt from
www bmrb wisc edu ftp pub bmrb statistics chem_shifts selected

But the Last updated format has changed from 1-26-2017 to 01/07/2005, so the line of the script that looks for that information could be changed to this:
StartChar,EndChar,Month,Day,Year = string.find( Line, "Last updated: (%d+)%/(%d+)%/(%d+)" )

The current version does have this format for the line reading the date , so we're in good shape!
