Subject: [PATCH] Merged V3.2 to HEAD    15154: Performance optimization for
 AuthorityDAO - based on 3.1E Share use case analysis.        - improves
 performance for create, find and general get of authorities via the DAO      
  - also potentially improves LDAP import etc. - anything that goes via Zones 
       - takes 3.2E performance ahead of 3.1E performance for Share use case
 (20,000 user and 2,000 site DB upgraded from 3.1.1E)    15447: Static asset
 web filter added to web.xml for Explorer client and Share webapp.        -
 Adds a 30 day public cache expiry header (configurable) to all static assets
 for performance and proxy usage        - Also prevents browsers such as IE
 causing conditional GET requests for images etc. on restart of the browser
