Start 1.4.10

ChangeLog for 1.4.9:

* Fix issue #35: overzealous caching meant that ref-only nodes were cached, and
  the equality on schema containers was only done on the loading JSON reference.

Francis Galiegue (3):
      Prepare for next version
      Do not consider anonymous schema contexts to be equal
      1.4.9
