feature request: default to "cross"

[ebowman]

I'll get to this before too long and happy to send a pull request. If someone else wants to get to it first, all the better. :)

Basically I want a project to be able to configure that running "release" automatically does "release cross". Otherwise it's too error prone -- we have a bunch of projects, some are "release cross" and some are just "release".

I'd love if we could settle on the right configuration name in advance?

releaseCrossByDefault := true

or something like that?

I agree that release should do the right thing, by detecting whether crossScalaVersions is non empty. I will add this SettingKey but keep the parameter to the release task for one version and add a (runtime) deprecation warning. Sounds good?
