This is what it took for me to use your package in ST2

For the most part these are very minor modifications and if you like the direction they are going I would gladly submit some more functionality as I use your plugin.

One important note would be that I think your packaging process, when submitting the plugin to ST package repository, will need to specify the package directory as "GoogleAppsScripts"; whereas, it currently uses "Google Apps Scripts" as the directory name for the plugin.  My development environment used the form with no spaces and I expect that failure to update the plugin deployment (or changing the code I submit) would result in failure to access settings files, credentials, et cetera.

Any feedback is welcome.

Until the next time...
