Fixed css loading

now CSS loads in this order; normalize.css, app.css, main.css
Optimized

All files have been fixed so there are no duplicate .js files being
loaded with the exception being timeline.min.js and timeline.js…. for
some reason both must be loaded for the timeline to work
Fixed 7 & 8

Fixed where the navigation says stage 7 instead of 7 & 8
Merge pull request #206 from SUNY-Albany-CCI-INF362/Fix-7&8
