Stop asking for the email scope
Improve command line parsing

- turn request type into an enum
- and then use args4j to parse it
- get rid of the explicit help option, because no args now spits out
help nicely (really everything does. you can’t get away from the help
menu!!)
Only ask for devstorage access when needed

- so on import, 2 scopes are used, and for everything else only the
genomics scope is used.
- we get around the limitations of the stored token by storing the 2
types of granted access in different places (user1 and user2 <— so
fancy i know)
