#287914 by Mike Wacker and David Lesieur: Add role assignment widget on user/edit and admin/user/user/create.
Starting with this release, the "Roles" tab only appears to users who do not have the "administer users" permission. Users who have access to the user edit form may now assign the roles from that form.
* Added documentation for PCRE Regex.
* Added documentation for auto-detection of keywords from search engine referer.
* Added Support 404 Searching if Apache Solr Search module is enabled
* Fixed some bugs
Added two helper methods for differentiating between Team/Pro and Enterprise easily. Moving to 1.0 release due to A) running out of version numbers in the old 0 branch and B) paucity of new features over time.
