Switch to LESS, modify structure

I switched to LESS for styles. I also completely reworked the document
structure, greatly simplifying the site.
Redo styles, remove files

I removed all files I didn't need and simplified the site to one page,
with new styles.
Tweak index page

I tweaked the index page to look right with the new styles.
Merge branch 'feature/less'
Remove Google

I removed all Google services.
