Fixes#394
Added bootstrap as dev-dependency
Removed jQuery dependency
People might use the SASS instead of LESS and/or might use the CSS only and not the JavaScript
When using bower the "main" property is used to specify the files that should be consumed by applications including the package as a dependency.
Without including the fonts in this array the glyphicons do not work correctly as the relative font paths do not work after the "main" files are copied into my projects public dir using tools like https://github.com/yatskevich/grunt-bower-task
For now I have manually copied the fonts dir in the location needed for my project. But by accepting this pull request this will not be necessary for me or for other people that use bower.
