Updating graphite

[Martin Hosken]

Dear Someone nice,

Any chance anyone could update the Graphite being used form 1.3.10 to the latest 1.3.12. There was a subtle behavioural change in 1.3.11 which wasn't reflected in the changelog (sorry) that it would be nice to get. And 1.3.12 brings in the latest hardening, which is always a nice thing to have.

TIA,
Martin Hosken.
