(profile) Added login partial

For historical purposes, it may be helpful to know that the code for this
partial was adapted from the code I wrote in the following file:

/application/views/auth/login_form.php

Since we don't need CodeIgniter anymore (thanks to Firebase), I can
move that CodeIgniter view into an AngularJS partial.
(index) Recreated index page

For historical purposes, it may be helpful to know that the code for this
partial was adapted from the code I wrote in the following files:

/application/views/header.php
/application/views/footer.php

Since we don't need CodeIgniter anymore (thanks to Firebase), I can
move these from CodeIgniter into a file with just raw HTML and Javascript.
This will be the base of the MyHonors application.
(index) Moved AngularJS app code into a separate file
(index) Added some comments and added missing data- prefixes
(AngularJS) Update from version 1.0.3 to 1.1.4
(Twitter Bootstrap) Update from version 2.2.2 to 2.3.1
(login) Changed PantherID input box to Email Address
(login) Added 'Forgot Password?' information
(profile) Add login controller
(profile) Add 'Sign up' partial and controller
(login) Remove test expression
(index) Include Firebase and FirebaseAuthClient library scripts
(profile) Integrate Firebase authentication into app

This code authenticates users via Firebase's Simple Login API. Upon
authorization, the API returns a user object that contains the UserID.
That UserID is then used to grab profile data for that user, and store
it in our Profile service (which can be injected into any controller).

I'll probably combine the FirebaseAuth and Profile services into one
single "User" service in the future. And I'll probably rename the Firebase
service to something generic like "Data".
