bacon v2.17.0

• default binding for 'c' in bacon.toml is now the new 'clippy-all' job which does what the old 'clippy' job was doing. 'clippy' job changed to not run on all targets. Default bacon.toml explain how to bind 'c' to clippy instead of 'clippy-all' - Fix #167
• expand env vars in job command unless the job specifies expand_env_vars = false - Fix #181
• some file events filtered out from watch (feedback welcome, especially if you notice some failures to recompute)
• parse test results even when tests are run with -q/--quiet - Thanks @narpfel
