Clean up, gam csv optimization

showCalSettings had nested loop over user
doLabel cleaned up, has starting point for parsing arguments passed in
from main
doUpdateUser has starting point for parsing arguments passed in from
main
gam csv processing is optimized. All '~~xxx~~' and '~xxx' substitutions
are found for each argument and loaded into a dictionary once before
the loop. During the loop, the substitutions can be performed quickly.
