Fixed the partials to support accessing targets which are not at the root directory for offline pages.  Added bootstrap-fluid-top open and close partials to allow the same functionality for the head of the document as bootstrap-fluid-bottom open and close did for the end of the body.  Changed booststrap-fluid top and bottom partials to use their corresponding open and close partials so that only one partial has to be modified if changes are desired.  Added a custom.js file for the same functionality that custom.css brings.  Updated the readme to mention the open and close partials and the custom js and css files.
