First pre-release of Twisted 12.3.0

Yes, you're reading well. For the first time ever (since 2008), we're actually pushing not 2, not 3, but 4 releases in a calendar year! Just to be able to use the fancy 12.3 version number.

But, apart from this nice label, this release also closes 158 tickets, among them:

• Support for local parallel testing in trial.
• A new "react" function to easily run a single asynchronous function in a script with the reactor.
• Partial support for Python 3.3.

Note that only Python 2.7 is supported on Windows now. We also require zope.interface 3.6.0 or newer.
