This is done in a backward-compatible manner: Once an existing profile is saved,
the new format is used.

Opening the new format with an old VLC version will work, too, but you will

macosx: move video filter control code to the global libvlccore control object since it does not belong in a window controller

The window is now ordered in front every time with a single click / shortcut

This bug resulted in failure of setting more than one video effect
filter on mavericks.

No functional changes

    - fix behavior of video-on-top by adapting to vout windows handling changes
    - set all windows to status level if one vout window has this level:
    This avoids that video effects panel, audio efffects panel etc. pp. are opened behind
    a vout window. Now they can be used as usual.

    Please note, that due to the type of these panels they do not remain visible
    when VLC gets inactive.

- fix some bugs
- avoid unnecessary reload of all settings when the user clicks Cancel in dialogs
- add error message when user enters a duplicate profile name (this is not supported by
the combo box

Clone and wall is not supported yet.

This way, you can keep multiple sets of filters with their respective values and switch on-the-fly
