Prevent log propagation globally

[Cybis320]

Prevented log propagation by setting log.propagate = False in the logger initialization and remove log.propagate = False from BufferedCapture.py.

unfortunately, no change. In my simple test case, the second call to initlogging() still causes infinite recursion.

ok, try addigg this at the start of initlogging() to reset stdout back to normal:

sys.stdout = sys.__stdout__

This resets stdout so that the 2nd call doesn't recurse. The later call to set it to point to a logger then works fine i think.
