Release v2.7.0

Feature/moderate requests (#165)

* Added menu entry for admin users to get to moderator page.

* Added moderator xhtml pages and flag in UserBean to identify moderator;
CommentBean needs still to be updated to show moderator in display

* Database - table "comment - added column moderated of type boolean;
this requires a regeneration of the affected POJOs using JOOQ;

* UserBean - added checks if user has Moderator Role;
UserBean - added variable to hold if user is on moderator details page (looks like the easiest way to keep this here, still ugly);
navbar.xhtml - bugfix, did not point to moderator sub section;
comment.xhtml - this is included in all details pages to render comments, now includes the prefix "Moderated by:" if the flag is set in the table comment on column moderated to true;
jooq/tables - regenerated using JOOQ generate

* rebased onto master
detail.xhtml - removed unused reference to ModeratorQueriesDetailBean:
DbUtil.java - set Moderated Flag on Comments when loaded from database;
DBUtil.java - set moderated flag when a new comment is created, this should only be set to true if the comment is created by a Moderator user in the moderator pages;
CommentBean.java - set moderated flag when the comment is created, only set if the user is doing this on the moderator pages and has the moderator role;
ResearcherQueriesBean.java - ensure moderator mode is deactivated for the user, we can not make sure the user bean set this correctly to false;
OwnerQueriesBean.java - ensure moderator mode is deactivated for the user, we can not make sure the user bean set this correctly to false;
