changed show data to include show_* in their name
implemented --sync-drive option to update command

* cleaned up __doc__ in ftrack.py
* originally had planned to add a totally new command `drive` but decided to
    just add a --sycn-drive option to the update command.
* --sync-drive should fully work but i haven't completely tested all use cases
* added oauth2 stuff for --sync-drive in util/oauth.py
* removed the drive command stuff because it's no longer needed
* code hasn't been refactored. going to do that in the next big commit.
