Add view suppliers view and suppliers API endpoint

This adds a simple view (mostly cribbed from the component view but
without the database stats) to view details for a given supplier,
currently lists the components they supply and name/email address pairs for
representatives however there's room to add fields for other representative
contact and company information as well.

On the API side this adds 3 endpoints:
    * api/suppliers: returns a list of all suppliers and their
    representatives
    * api/suppliers/<id>: returns a supplier object containing the
    representatives for the given supplier
    * api/suppliers/<id>/components: returns a supplier object
    containing a list of components supplied by the given supplier

This also contains minor documentation and base template changes, fixing
the navigation menu to use class="active" on the currently selected page
(previously didn't work due to page_name capitalization)
