[PATCH] Fix Engine<.., MultiPatch<..> >::makeOwnCopy()

[Richard Guenther]

Hi!

Currently for a multipatch engine makeOwnCopy() does no good (it doesnt
copy), it seems because just calling makeOwnCopy() on the
RefCountedBlockPtr does not copy the underlying engines. I didnt figure
out why and so came up with the following fix which works for me. I have
also an updated Field/BasicTest3.cpp which now checks every engine
combination for makeOwnCopy and it now succeeds for both MultiPatch<Brick>
and MultiPatch<Remote<Brick> >.

Ok to apply?

Richard.

	* Engine/MultiPatchEngine.cpp: do makeOwnCopy() manually.
