Improvements

• Discovered main classes are now sorted. #1180 by @kretes
• Implemented a new mechanism of forking javac, whereby errors are captured. Also more likely to run in-process. #1702 by [@jsuereth][jsuereth]
• Adds project-level dependency exclusions. See below.

Fixes

• Javac warnings now always treated as warnings. #1702/#875 by [@jsuereth][jsuereth]
• compilerReporter now fed to javac during incremental compilation. #1542 by [@jsuereth][jsuereth]
• ignore hidden build files from the build. #1746 by @j-keck

Project-level dependency exclusions

sbt 0.13.8 adds project-level dependency exclusions:

excludeDependencies += "org.apache.logging.log4j"
excludeDependencies += "com.example" %% "foo"

In the first example, all artifacts from the organization "org.apache.logging.log4j" are excluded from the managed dependency. In the second example, artifacts with the organization "com.example" and the name "foo" cross versioned to the current scalaVersion are excluded.
