Bazaar Explorer 1.0beta ready for testing

[Ian Clatworthy]

I'm planning to release explorer 1.0beta around my Friday morning,
around 36 hours from now. This version will be bundled with bzr 2.1.0 so
I'd like to ensure the quality is as least as good as previous releases.

There's are a *heap* of nice new features so please grab rev 401, read
NEWS and test furiously!

Alexander,

Could you upload the latest message strings and ping bzr-l10n please?

Thanks,
Ian C.
