[NEW] Xmo'd: model comments that start with -- are passed as args to mogenerator (David LeBer)

i.e: Comments that look like:

xmod
--base-class 'MYMOBase'
Blah blah, other comments, etc blah

Will result in:
do shell script /usr/bin/mogenerator --model 'PATH_TO_MODEL' --output-dir 'OUTPUT_PATH' --base-class 'MYMOBase'
