v0.4.0

• Fixed a memory leak bug that caused the server to crash after many runs.
• Better coverage reports.
  • Coverage reports are now cached per-test-file. This leads to a more accurate report when changing the test files.
  • Coverage reports are now generated in a separate process. This also makes the server crash less often.
• Simpler test entry configuration. No more TestBed global in your test entry file.
• Test framework adapters. As test-bed becomes more sophisticated, more integration with the test framework (e.g. Mocha) is required. Forcing users to update their test entry file every time a new version is released is no good. test-bed now ships with adapters for test frameworks (only Mocha for now).
