    Fix failure to update version group screen when adding languages or projects.

    This is apparently only happening with Wildfly for some reason. EAP does not seem to have that problem.
    Solved by running one of the involved a4j:jsFunction in a separate 'context' by using an immediate setTimeout.

    Correct functional test issue.

    The version filter may end up with the wrong results if a user is able to change the search query before a previous request for filtering has returned.

    Use Richfaces’ column sorting capabilities instead of custom ones.

    Richfaces has changed the behaviour of their column sorting slightly, but it should not be a problem for existing users.

    Improve usability on tables with auto-filter columns.

    This seems to only work on EAP 6.3 and over.
    Still need to add an ajax indicator when there is a filtering operation going on in the background.
