Enable the use of non-origin oAuth urls + new window options

[jookyboi]

I have an Angular2 app which uses a separate Rails/Devise backend. I needed the oAuth flow to hit that server rather than the host which serves my frontend client. This pull helps deal with that.

• Added new oAuthBase option for the oAuth flow
• Added new apiBase option for other API calls
• Added a [string:string] object oAuthWindowOptions to allow users to set additional options on the new window (ex. oAuthWindowOptions: { width: '800', height: '600' })
• I switched to using backticks for strings which have variable interpolation. It didn't compile with just straight up single-quotes for me
• Updated docs

Thanks for taking the lead on an excellent package.

It seems perfect to me

I think so too. Didn't have time to test it yet.

@neroniaky that will even fix the issue I mentioned in #119 , the issue is with the single quote chars when building the oauth path, it should be ` char so the literal string replacing works.

Thanks. Since the PR was initially opened, I also added an optional resetPasswordToken to updatePassword() so that users going through the Devise reset-password flow could update their password.

I added an optional name? as well to the RegisterData model since I needed it for display.
