Setup hippo theme so bower link can be used with end-projects

In order to do quicker development of front-end projects we should be able to make changes in hippo theme and let those changes propagate to end projects without having to commit/deploy to nexus and then reinstalling hippo theme as bower dependency.

Bower api method 'link' can be used for this but it currently can not because the local development folder structure is different from the distribution folder structure.

• Change folder structure of hippo theme so that bower link can be used
• add Grunt task to watch without using livereload, because you can not run 2 grunt watch tasks that both have a livereload option set to true.
