start storing incoming MediaEntry on a new Media field on PrimitiveBaseShape

This allows the media texture to persist in memory - logging in and out will redisplay it (after a click) though navigation will be lost
Next need to implement media uri on prim and delegate more incoming llsd parsing to libomv
