Feature request: Have `wait` take a timeout

[adamtheturtle]

Thank you for the software.

I am looking to replace my current subprocess wrapper with sarge. One blocker - the wait function does not take a timeout.

See https://docs.python.org/3/library/subprocess.html#subprocess.Popen.wait for the timeout I am talking about.

The timeout parameter was only added to subprocess.Popen.wait in Python 3.3 - so adding this would need to handle older versions, correctly, too.

Fix #44: implement an optional timeout in Command.wait (for Python >= 3.3).
