Set upon RPC version logic and META to start work on version 13.12

Note, we are switching to the ubuntu version numbering scheme:
last two digits of the year for the major version number
month number for the minor version number
13.12 == 2013 December
Fix uninitalized variable in modified version number logic
Make the slurm super user test more robust

We've seen expect not pick up the full user name in some cases,
but truncate it.
