[gimp-help-2] Update Preferences/Help.

[Sven Claussner <sclaussner src gnome org>]

commit a9692aea2603a95ad8734240749305c3cdb784d7
Author: Sven Claussner <sclaussner src gnome org>
Date:   Wed Jul 23 20:33:56 2014 +0200

    Update Preferences/Help.
    
    If the internal GIMP help browser is not installed, then the next 2.8
    release will hide the listbox 'Help Browser to use' and always open the
    help files in the system's standard web browser.
    Remove obsolete description 'Web browser to use'. This option was
    removed from GIMP already in 2009.
    Remove obsolete line 'Linux screenshot' because it doesn't provide
    useful information in this context and let's assume that this feature
    only works on Linux, which is not the case.
