Fixes DEVELOPER-413

I'm using the forums.yml which may go away, we'll see what we can do
with searchisko
DEVELOPER-357 - author (from name) and contributors (from email) mapping
configured for jbossdeveloper_quickstart content type. 
Persistence enabled for all jbossdeveloper content types to make DCP
backend of JBoss Developer site more reliable for production use (allows
rebuild of DCP search indices without data push from site build).
DEVELOPER-357 jbossdeveloper_quickstart author mapping reconfigured to
ignore duplicit lookups over name
DEVELOPER-127 - added jbossdeveloper_website content type used for
website indexing
DEVELOPER-127 - added website_project_code field into
jbossdeveloper_website es mapping
DEVELOPER-127 - project mapper added
DEVELOPER-243 Store developer materials form search criteria.

The search criteria is stored in the browser's local storage and is
re-used whenever the user browses to the search form page.

Removed duplicate checkbox in the search form. Refactored some JS
variables.
