Global hook to handle failed tests

[rustkt]

I use ava in my project as testing framework, needs to scaffold the processing of errors.

Can ava add an error handler globally (across all test files), triggered if each test fails?

Any hooks need to be registered in each test file, but you could do that in a helper script and include it via the require option in the AVA's package.json configuration.

However you can't currently access the test status from such hooks. We're open to that feature though, see #840.
