Getting errors from the logs shortcut

[parkeraa]

It would be convenient to have a command like "pyrolab status" that would print out if the daemon is running or not, and prints out any warnings or critical errors that have occurred since pyrolab last went up. This would make it a lot easier to debug problems with a daemon/service without having to export the logs every time.

This could also be done in the pyrolab ps command. If a process has died, report the corresponding errors. Also, since pyrolab will retry forever, make sure to only print the most recent instance of a given error.
