Explicitly use components/jquery

jquery used to be a shorthand for components/jquery, while jQuery referred to
jquery/jquery.

Recently the jQuery team requested that jquery point to jquery/jquery as well.

Bugs are now open with both projects:

http://bugs.jquery.com/ticket/14798
https://github.com/bower/bower/issues/1118

Until this issue is resolved, we should be explicit about what version we want.
