Celluloid 0.13 is out!

https://github.com/celluloid/celluloid

This was supposed to be the last release before 1.0, but as the release
cycle dragged on I felt I needed to get this version out there sooner as it
includes neat new features:

- Inter-actor stack traces: previously Celluloid's stack traces were hard
to interpret because they stopped at the boundaries between actors. Now
Celluloid can trace calls across actors, assembling calls into a single
stack trace that shows where calls between actors were made.
- Celluloid::Condition: ConditionVariable-like signaling between tasks
within the same actor or between actors

Another important change answers an often raised complaint: Celluloid
starts some default services and installs an exit handler which does a
clean shutdown and prints a small report. While I feel these features are
important for people writing large programs with Celluloid, people just
getting started found this annoying.

Starting in Celluloid 0.13, you will now need to do:

    require 'celluloid/autostart'

In order to launch the default services and install the exit handler. If
you only do:

    require 'celluloid'

...no default services will be launched and no exit handler will be
installed.

Full changelog follows:

* API change: Require Celluloid with: require 'celluloid/autostart' to
automatically start support actors and configure at_exit handler which
automatically terminates all actors.
* API change: use_mailbox has been removed
* API change: finalizers must be declared with "finalize :my_finalizer"
* Bugfix: receivers don't crash when methods are called incorrectly
* Celluloid::Condition provides ConditionVariable-like signaling
* Shutdown timeout reduced to 10 seconds
* Stack traces across inter-actor calls! Should make Celluloid backtraces
much easier to understand
* Celluloid#call_chain_id provides UUIDs for calls across actors
* Give all thread locals a :celluloid_* prefix
