JS and WUI tidy up

[rgrp]

Consolidate js. Remove cruft.

• Move stuff to vendor
  • Have all vendor libs local (?)
  • jquery, jquery-ui etc
• Consolidate autocomplete to use jquery-ui
  • package autocomplete (groups)
  • tag autocomplete (package)
  • user autocomplete (authz group create)
    • turns out that authz group edit had autocomplete disabled so refactoring meant enabling ...
• Move forms.css into main
• Remove tag cloud from front page (can be example going forward)
• Remove bookmarklet (since in wiki at: ​http://wiki.ckan.net/Managing_Data_Packages#How_Do_I_Install_the_CKAN_Bookmarklet.3F)
• Move name slug generation into standard js and clean up

Possible:

1. JS unit tests for the given pages ...
2. Option to use external site to serve js and css (e.g. CDN)
