[gjs] Send in prototype to JS_NewObject

[Philip Chimento <pchimento src gnome org>]

commit bc8f143e4a3a5407c65ebbf500d0c54598bb6104
Author: Johan Dahlin <johan gnome org>
Date:   Tue Mar 30 20:01:45 2010 -0300

    Send in prototype to JS_NewObject
    
    Send in a reference to the prototype to JS_NewObject, this
    makes sure that the created object contains all properties from
    the prototypes. This makes it possible to call Cairo.Context methods
    on wrappers created from API created through introspection.
