Upcoming release of RQ 1.0 #80

Hey there, just want to give a heads up about the next major RQ release, v1.0. I plan on releasing this new version in the second half of Feb (although this may change due to work commitments).

This release will have a few backward incompatible changes, the biggest one is the introduction of FailedJobRegistry that replaces FailedQueue. I have documented the new registry here.

The branch for the upcoming release is here: https://github.com/rq/rq/tree/v1.0

Let me know if there's any questions. Thanks!
