SPECS2-4.0.0

Dependency-free version!

specs2-core is finally dependency-free and doesn't need to be built for various versions of Scalaz.
specs2-core is also now available for Scala.js

See the blog post for more information.

Changes

• project dropped the support for Scala 2.10
• core removed the dependency on Scalaz, there is now a specs2-fp module implementing a small amount of FP concepts
  to support the internal implementation of specs2 itself
• scalaz moved DisjunctionMatchers and ValidationMatchers to that module
• scalaz dropped the support for scalaz 7.0

Improvements

• introduced a org.specs2.specification.Retries trait extending AroundEach to retry each example
• introduced org.specs2.specification.core.OwnEnv/OwnExecutionEnv traits to isolate the execution environments of
  some specifications
• added addSections to "unit" specifications to enclose each block with section markers and allow it to be selected
  with include on the command line
• form display the actual value instead of the expected one for a Prop (this might be revisited in the future)

Fixes

• fixed the execution with stopOnXXX arguments for a sequential spec
• core the Result.foreach method must stop evaluating elements if there is an issue
