[Sanford Armstrong <sharm src gnome org>]

    On Windows, manipulate PATH and GTK_BASEPATH environment variables to ensure the correct GTK+ is used. Fixes bug #558314.
    
    The value prepended to PATH can be overridden by setting the TOMBOY_PATH_PREFIX environment variable, and the value set to GTK_BASEPATH can be overridden with the TOMBOY_GTK_BASEPATH environment variable.
