updates to the SCSS files, style sheet and header file

I removed the global.scss and the global.css style sheet and replaced
it to follow the orginal structre to complile to the style.css style
sheet. I added a type, color, and global SCSS files that will import to
style.scss. There also should be a codekit config file that will make
codekit compile the style.scss file into the root folder. I also enable
the meta viewport tag for mobile that was orginally commented out.
