Document what go.tools/importer commit pythia works with -- or vendor it

My go.tools directory is at tip:

go.tools$ hg summary
parent: 657:a1ba4a15f741 tip
 go.tools/importer: API rethink.

However, go get fails:

I'd be happy to check out a different importer version, if it gets documented.

Better yet, you could vendor importer (via e.g. godep or goven), so that go get guaranteed to work...

Thanks!

Thanks for the report, I've updated Pythia to the new API. I'm planning to vendor it soon.

[fzipp]

The go.tools dependencies are vendored now.

Nice! Thanks.
