Hrm, this is replacing the previous ones with buffer, effect, and the
SRCs?  I actually thought most of the types could be useful there - I
can see from a sequencing point of view we might want to start buffers
first, and the SRC and encoder/decoder widgets are going to be useful
when we're tracking more than just simple routing with DAPM.  The only
bit I was really concerned about was the overlap between pipeline and
effect.
