Workaround OAuth woes by allowing user specified Oauth credentials.

[colemickens]

This allows the user to bypass current problems with gdrive by specifying their own oauth app credentials.

They can either place in this in ~/.gdrive/oauthClient.json or pass it as a command line flag --oauth-credentials.

This also converts to go mod / go modules because Godeps has taken enough from all of us.

Oh... I guess I duplicated #476. cc: @ppbrown @Exonip.

Anyway, this seems a bit more extensible, allows for command line override, lets the user use their own credentials because shared creds are likely to just be re-flagged without something else being done. (and gets rid of Godeps)

It worked. Thank you very much.

Does this allow for variable length oauth credentials, ie addresses my issue?

@caseykey In short, yes, it would allow you to use those credentials. This is a fundamentally less hacky approach that editting the binary (no slight on that approach, it's a smart, easy option that will work for many people!).
