    More usability fixes.

    - Make autocompletes only fire when there is a change to the search text (avoid ctrl keys), and after the user has stopped typing.
    - Search for maintainers is now case insensitive.
    - Add a loader when adding maintainers (currently only at the version group page).

    Make the requests from list filters have a short (500ms) delay before being sent to the server.

    This means less requests sent to the server.
    This generates some unnecessary warning messages on the logs. See the following for more details:

    Usability fixes.

    Includes changes to the autocomplete controller so that it shows ajax indicators as well as resetting to its initial state when it needs to.
    When Escape key is hit on the autocomplete, the result list is hidden and the whole text is selected.
    When searching for projects, the presence of spaces no longer omits results.
    Remove some default Seam messages that conflict with application defined messages.
    Version Group page changes:
    Refactor the page so that when adding or removing versions, languages and maintainers, there are ajax indicators for these operations.
    Make sure the loaded tab (according to the URL) is displayed before sending off the initial ajax requests.
