Jest by default now also recognizes files ending in .spec.js and .test.js as test files.
Completely replaced most Jasmine matchers with new Jest matchers.
Rewrote Jest's CLI output for test failures and summaries.
Added --env option to override the default test environment.

Jest uses verbose mode when running a single test file.
Console messages are now buffered and printed along with the test results.

Jest now works properly with directories that have special characters in them.
Improvements to Jest's own test infra by merging integration and unit tests. Code coverage is now collected for Jest.
