Remove library jQuery Waypoints and its usages because now I'm only have got one section visible at time.
Add Bootstrap tabs to handle site sections;
Add "Top" section with Instagram most popular photos;
Remove scrollTo, footer, and remaining Waypoints usages;
Merge branch 'newDesign'

Conflicts:
	js/app/ui/index.js
Fix broken merge and restore scrollTo function.
