chore(Rakefile): various build script changes

- restructure rake tasks

  this splits up the concatination and minification into two
  tasks so that we can just build angular.js quickly without wasting
  time with minification which is often not needed when just debugging
  some issue on 3rd party site.

- use symlinks when creating final zip file

- switch from btar to zip

- get rid of version numbers from filenames

- rewrite version numbers in all index files

Closes #1226
