Trigger (Oct 10, Julie)

Additional bits were added to the trigger word (l1T->trigWord) to hold the GEM summary information.
This resulted in changes in the TRGWORD distribution. However, this caused a problem with the
merit tuple variable GltWord, which is identical to trigWord except that there was an assumption
in AnalysisNtuple::GltValsTool that the variable should be less than 1024, so the routine set GltWord
to zero if trigWord > 1024. The addition of the higher order bits made this assumption incorrect. This
caused large changes in all the distributions which depend on a trigger cut using GltWord (i.e. all
the distributions with names consisting of mixed upper and lower case letters).
