Inconsistent Naming between oauth api and OAuth.ts

[SReject]

The property naming with OAuth.ts for the OAuthProvider constructor's options.tokens is inconsistent with what the OAuth api returns equating to the program having to do some middle-man-mutating of the api's response before calling the OAuth constructor.

API Uses	OAuth.ts Uses
client_id	clientId
client_secret	secret
access_token	access
refresh_token	refresh
expires_in	expires*

*) This is fine as the two names refer to two different pieces of data (API returns a number, OAuth.ts expects a ISO date string)

This is predominately only an issue with the setTokens() function. Since its called from the constructor it inhibits the user/app from passing an oauth api response directly into the constructor.
