Bring some sanity back to the link colors

I had variables all over the place, using specific colors in
different sections. Now I'm only using two variables for all my
link colors, instead of six.

Doing this let me remove a lot of styling, and my link colors are a
lot easier to deal with.
Fix space between masthead and content on small displays
Prevent zooming in on mobile
Fix masthead image following you on mobile
Disable Skrollr on mobile
Remove icomoon fonts

To be replaced by FontAwesome
Add social buttons

Icons from the wonderful FontAwesome
Move around masthead comments
Tweak intro background color
Align intro content to the left on small displays
Remove skrollr-body ID

This was only used for making things work properly on mobile
devices. I've opted to disable Skrollr on mobile so I can get a
release out faster.
Don't use responsive masthead height on smaller displays
Pad the sides of the page
Decrease masthead font size on small displays
Disable the Susy grid overlay
