samurai 0.2

New features

• Honor ninja_required_version in build files.
• Match behavior of newly released ninja 1.8.x.
  • Re-run commands which started to write their output, but didn't succeed.
  • Close extra copy of write-end of command output pipe in subprocesses.

Bug fixes

• Makefile is now POSIX compliant.
• .ninja_log parsing counted entries incorrectly, preventing recompaction.
• Console output was mistakenly suppressed when console job was queued but not running.
• If phony inputs are missing for an edge with restat = 1, a garbage mtime was used when calculating mtime .ninja_log entry.
