Title: Problem: need way to capture log data in any binding

Solution: allow zsys to send log data to a PUB socket. zsys_logsender
defines an endpoint that log data will be sent to. This can also be
set by the ZSYS_LOGSENDER environment variable.

Note: also fixed some errors in environment variable handling (was using the wrong names for some case).
