/*
    Modified to insure no shapeshifting spells are castable upon
    mounted targets.  This prevents problems that can occur due
    to dismounting after shape shifting, or other issues that can
    occur due to preserved appearances getting out of synch.

    This can additional check can be disabled by setting the variable
    X3_NO_SHAPESHIFT_SPELL_CHECK to 1 on the module object.  If this
    variable is set then this script will function as it did prior to
    this modification.
