Subject: [PATCH] Prefer the locally installed version of AVA.

This hunts for AVA in the locally installed project, and runs that
CLI instead of the globally installed one.

Fixes #157.

 Files starting with `_` are ignored. This can be useful for having helpers in the same directory as your test files.
 
+*WARNING: NON-STANDARD BEHAVIOR:* The AVA CLI will always try to find and use your projects local install of AVA. This is true even when you run the global `ava` command. This non-standard behavior solves an important [issue](https://github.com/sindresorhus/ava/issues/157), and should have no impact on everyday use.
