Fixed a long standing bug in IMB_dupImBuf: refcounter should be better 0
within the duplicated ImBuf...

Finally removed this strange STRIPELEM_META mumbo jumbo.

On a way to asset management: made METAs behave like true input strips:
* proxying should work
* input filter options should work (including transform and color balance :)
* IPOs now work in replace mode
