genscript: remove --nolog switch

The new method is to turn on condebug prior to script execution, then turn off
condebug at the end of the script.
genscript: look for "CL_SignonReply: 2" instead of "START "

We found that this works for most cases.  If this happens to not work, then we
can cheat by editing qconsole.log to move "CL_SignonReply: 2" around.
