Add -l flag to allow 'module load XXX' to work

If I try to run a qsub job on geo.bu.edu and it requires modules
I've loaded in my .bashrc (e.g., 'module load hdf5' in this case),
the job only works if my script has a '-l' flag after the shebang.

Apparently some users don't have this issue, but it doesn't seem like
the flag hurts anything even when its not needed.
fix to dbfile.input.insert

fix wrong input select statement. it requires both start and end date
to do proper select.

copy variables of interest to a new file. Don't think we actually want APARpct and ZL, but left them for now.

Every variable has lat,lon,time dimensions. 1 exception is time variable. DTIME and time are also duplicates, which needs to be fixed.

Variables with conversions were not completely re-written as in previous version - this preserves more variable attribute information.

Panoply does not recognize the missing values for air_pressure and CO2 properly. All other variables plot normally
