New Login Experience supporting Identity providers other than Twitter.

[harunkumars]

Currently our home page simply shows a "Login with Twitter" button.

Now that we have Github coming up as an alternate login option.
This button should be replaced with a generic Login button.

Clicking on Login button should take us to a page, which should allow the User to Login with Twitter/Github or any other provider we may add in the future

The new Login page will have two columns.

The column on the left should have buttons for Logging in with Twitter, Github or any other Identify provider we may add eventually.

The column on the right will have a form to Login with Email / Password.
There should also be a link at the bottom of the form to allow Users to Register.

Something like :)
Login with Twitter | Email login form.
Login with Github | Signup link
