    app: move OpenCL settings into the Playground.
    
    After discussions on IRC, it was decided that our current level of
    support of OpenCL was not good enough. As a normal settings, people just
    see it as a normal acceleration checkbox, even despite the warning text
    and emoticone saying the opposite (i.e. it may even slow things down in
    some cases).
    Basically this feature needs more love to be back into mainstream
    Preferences.
