gllamm estimation - minor

updated log file name, when drop if missing, only check smd_on_call
exposure variable instead of the rest since want to have the same sample
as for the meqrlogit estimation
meqrlogit - new do file

runs the models with the 4 additional exposure variables
did in separate do file so don't over write the results we have for
smd_on_call
Also don't create output table 1 for these additional variables, just
run regressions to get logs to use. Saves results so if need to get
tables, should be able to add them back in
