Rearrange folder structure

This makes the folder structure more shallow, which should hopefully
make it easier to deal with.
Reformat router and add "use strict"
Update README with new installation instructions
Use Meteorite instead of vanilla Meteor
Abstract routes to library

Instead of keeping them all in one file, this moves individual routes
to their own files.
Remove "to troubleshoot your error" from README
Add "use strict" to shuffler
Remove weird spacing from .gitignore
Merge pull request #124 from christianbundy/master
