Create basic draft of sponsor page

Simple first iteration of the sponsor page

Still need:
-Assets (put gray circles instead)
-Decisions on what the banner colors(or images) will be

Some really quick feedback would be helpful!
I'm not sure this is cleaner but doing

```ruby
resource :page, controller: 'pages', only: [], path: '' do
  get :sponsors
end
```
will let you add more static pages with just another ```get :page_name``` line. This changes the old path to sponsors_page_path. Should probably talk about this a bit more since whether or not to use something like this depends on whether we have more static pages.
