v0.12.0

ALL

• Print out walltime and other runtime stats unless -q/--quiet is specified
• Limit the number files open to 80% of hard-limit or --max-open-files if specified (zero means no limit)

RLINK

• Allow setting the --update path to be exclusive using --update-exclusive flag, meaning only files present there may be hard-linked from src

RCMP

• BREAKING: make passing the log file to rcmp optional, use --log=<file path> syntax
• Fix how we log a file missing from src
• Return 1 on mismatch and 2 on errors similar to diff, previously we would return 1 on errors and 0 otherwise
