Development v1.0.0

[Athroniaeth]

• Modified --lock argument, now target only test with lock fixture
• The tests with the lock fixture had skipped status, now they have passed status
• The tests without the lock fixture had passed status, now they have skipped status
• Add pickle extension for lock.lock to support more types of data
• Now pickle is the default extension for lock.lock if no extension is specified
  -If test use --lock and --clean argument, then clean all unused cache files
  -If test use --lock and --clean argument and --only-skip argument, then do anything, it's certainly a mistake (why clean only test with existing lock ?)
• If test use --lock and --clean argument and --simulate argument, list all unused cache files who will be removed without remove them.
• If test use --lock and --clean argument and --lock-date argument, thrown exception (can't lock a remove cache file)
