Use uglify for concatenating, update CONTRIBUTING

- Uglify for concatenating enables sourcemap support
- Add sourcemaps
- Fix `Candy.Core.log`: Shows now correct line numbers
  - we should test if it works in IE still (@pstadler likes to test?)
- Remove grunt-contrib-concat
- Update CONTRIBUTING.md with vagrant install
  - FIXME: Make this easier

 ### How to contribute
 A few hopefully helpful hints to contributing to Candy
 
+#### Using vagrant
+1. [Fork](https://help.github.com/articles/fork-a-repo) Candy
+2. [Install Vagrant](http://vagrantup.com/)
+3. Follow instructions [for Candy Vagrant](https://github.com/candy-chat/vagrant)
+4. Change the remote in the `candy` and `candy-plugins` repos: `git remote set-url origin git://github.com/YOURNAME/candy` (or candy-plugins)
+5. Create a branch based on the `dev` branch (`git checkout -B my-awesome-feature`)
+6. Run `grunt watch` to automatically run jshint (syntax checker) and the build of `candy.bundle.js` and `candy.min.js` while developing.
+7. Make your changes, fix eventual *jshint* errors & push them back to your fork
+8. Create a [pull request](https://help.github.com/articles/using-pull-requests)
+
+
+#### On your own machine
+Please note that you should have a working XMPP server to test your changes (the vagrant way does already have a working XMPP server).
