Updated link color; Added nav element

Changed link color to orange, updated SASS file with recent CSS changes,
Made <nav> element with some <hr>'s that I want to skew and then expand
to show a list of links or something. Maybe when you hover it will
square, and on click the top of the page will slide down to show links?
That sounds pretty cool.
Improved nav, still no skew

Set the nav to fixed position and added top element to hold links. Still
don't have button skewing, but I'll get there.
