This replace global sleep time of the daemon

Build and commit command/duration was printed at the end of the log instead
of the time they are available

- Takes config object
- Display build and commit duration
- Improve error reporting

- New "cache" system, using persistant data dir
- Change argv options (remove --cache-path)

KISS approach

Aurbot take a list of package, use external build/push command and compare
with AUR update
