Expose KnownGraph off of VersionedFiles
handle ghosts (needs tests, doesn't seem to effect performance)
list(tuple[1:]) is a couple ms slower than using my own loop.
Net effect is:
  time bzr log -n0 -r -10..-1
  real    0m2.559s

  time wbzr log -n0 -r -10..-1
  real    0m1.170s

  time bzr log -n1 -r -10..-1
  real    0m0.453s

So the overhead for the extra graph is down from 2.1s to 0.7s
