0.6.0

• jest now reports the number of tests that were run instead of the number of test files.
• Added a --json option to print test results as JSON.
• Changed the preprocessor API. A preprocessor now receives the script, file and config. The cache key function receives the script, file and stringified config to be able to create consistent hashes.
• Removed node-worker-pool in favor of node-worker-farm (#540).
• toEqual now also checks the internal class name of an object. This fixes invalid tests like expect([]).toEqual({}) which were previously passing.
• Added the option to provide map modules to stub modules by providing the moduleNameMapper config option.
• Allow to specify a custom testRunner in the configuration (#531).
• Added a --no-cache option to make it easier to debug preprocessor scripts.
• Fix code coverage on windows (#499).
