SST parameter value uppercase/lowercase problem

Created by: pnorbert

I observed that FirstTimestepPrecious, "TRUE" is not working, while "true" does. The documentation btw shows "TRUE" and "yes" as examples. Values should be converted to lowercase before comparing them so that all bool flags work the same.

Another discrepancy is that some flags are On/Off (BP), others are yes/no or true/false. But this ticket is just pointing out the problem in SST.
