Added bower support

Have added bower.json.  Needed to version the /dist folder as bower expects a compiled version of the code.  Some extra steps are needed.

1. A new tag for the current version with bower support with the /dist folder versioned.
2. Have added jquery and jshamcrest as bower dependencies.  Maybe the build script an be updated to use the dependencies in  bower_components insted of distributing them in the /src folder thereby not needing to version thrid pary libraries in git.
3. Needs to be published to bower as described [here](http://blog.stackfull.com/2013/05/publishing-bower-components/), I cannot do this as it should be pointing to the cleishm/jsmockito git repo.
