#1065 Avoid SIGPIPE errors in windows mode

SIGPIPE is only available on Unix. Add try/except so that this
import does not crash ogclient when running in Windows mode.

Only assign SIG_DFL handler to SIGPIPE when mode is not windows.

Prefer signal.signal over signal alone to better distinguish module from
function.
