CSS Cleanup and File Structure Updates

* Altered and Added folders and files for the Content structure of the
site. We now have all of our pages in place, ready to have content
loaded and templates built.

* Made slight CSS refinements, including lowering the font-size of the
navigation to .9em, changing the nav li padding to 10px to shorten the
overall height of the top bar, and fixing the top bar to the top of the
viewport. I'll stop writing 'top' now as it is no longer a word.

* Still have not solved the fact that the fonts are much heavier than
in the priginal design. This is my bad for not accounting for the
difference in font rendering between photoshop and the browser when
doing the mockups.

* Swapped out the png logo with the wrong colors for the svg one with
the right colors.

* General cleanup on CSS -- added Comments to denote sections,
alphabetized properties and adjust tabs and ending brackets to be tidier
