Fixed bug in NetworkEvents::createZmqContext.  Added Python example script for sending network events.

Included unistd.h for successful Linux compile, known fix from https://github.com/open-ephys/GUI/pull/150

0MQ is included, but not linked (unless you define it in
NetworkEvents.h).
Redrawing events are not called for some reason.

Fixed a bug in conditional operators to compile eCube support
Added exception handling code to allow for errors during source creation

Open-Ephys GUI configuration file for loading up 2 headstages intan2132_16ch (part #C3334) connected on A and B port with channel mapping reordered on the acquisition board.

Open-Ephys GUI configuration file to load the correct channel mapping for intan2132 16ch (part #C3334)

however, doesnt send empty command strings to the leds, so expect random
behaviour on startup

to reflect that it assumes criss-cross loading
and fixed pin swap 1<->8

Seems to be correct for the flexDrive 64ch EIB, see
https://open-ephys.atlassian.net/wiki/display/OEW/Omnetics+2x32

Due to the update to Juce 2 and the removal of IntanThread all of the specific windows dependencies are not needed anymore.
