Feature request: add account to use when --open

[krank]

Those of us who regularly use multiple google accounts would, I think, greatly appreciate the ability to specify which account to be used for --open.

Example: I'm logged in (on the web side of things, in the browser) as both [email protected] and, using Google's multi-account functionality, [email protected] (which is still a google account, just connected to a corporate domain). The [email protected] account is my default.

Now, it doesn't matter if the project I'm working on is owned by [email protected] or by [email protected] – if I do a clasp --open then the browser will try to open the project as [email protected].

I'd like the ability to do, for instance:

clasp --open --account [email protected]

Or something like that, anyways. Sorry if unclear.
