Upgrade to Scalaz 7.1.x series.

This is the latest stable release of Scalaz. We upgrade it only in the
default space. There's another scalaz defined as "scalaz-210" and is used
for building sbt plugins. We keep it at 7.0.x to avoid problems with
sbteclipse. Once sbteclipse upgrades to latest scalaz, we should move
that version in our config too.

Remove sbt-library-full from community build

[Quoth @dragos](> https://github.com/dragos/sbt-full-library/pull/3#issuecomment-56634966):

> This project is a failed experiment. I don't think this should be

> the same purpose (to obtain OSGi-via-maven artifacts).

Use sbt 0.13 for building zinc.

Let's get rid of override of sbt version when building zinc. Zinc has
already migrated to sbt 0.13 and it doesn't have to be treated specially.
Remove sbt-version-overrides in each project.

We can override sbt version at the build level which propagates to
all projects defined in given build. It cuts down on boilerplate in the
config.

Upgrade to Scala 2.11.2 used for extraction.
