Issue #24: Create a 'Contact Us' page

Figured out how to make the contact form follow the mobile design
put in place by ThemeBrain. Rather than copying and modifying all
the responsive CSS files, I just created a new 'slcc-mobile.css'
file, and modified the mobile directives affecting the form in
this case.

We can use this technique for other responsive issues that arise,
as well.
