Removed the Layout file for the Sports index page

Rails has the option to render pages from the Controller with a template of sorts, so that you can limit redundancies within files.  However, to make things simpler to edit and such, we're probably better of only using these sometimes.  While I originally had the sports index page rendering within it's own template file, I realized that this was ridiculously redundant and instead just condensed it all to one file.
Database Migrations

- Added Users
- Added an "alerts" column to Sports
- Changed "content" from "string" to "text"
- Removed limit on "content"
Added schema information
Made all links white.

In hindsight, this was probably a really bad idea, but I'll probably fix it at some point later on
See previous commit about Sports Index page

I did the same thing here to the general sports pages
Added User model and controller

I think
Updated routes
