GH -> GS drush script openscholar/openscholar#3394

`drush @site gh2gs --labels=feature_request --style=idea --remove-labels=TRUE`

Drush script sends tickets from github to getsatisfaction
* Only sends tickets matching a set of labels
* Each run will create a different style of GS topic.  Default is question.
* CLI option lets you specify what happens to the set of labels afterwards.  IE if you label 30 tickets as getsatisfaction, it can remove that label on a success, so that they won't be sent over again.
* New topics will be linked to old gh ticket.
