The user can now select up to 5 different phase detectors within the same
module, each triggered on one of four different phases. Each can have
its own unique input channel, output channel, and gate. This is a vast
improvement over what we were dealing with beforehand.

This should help reduce overheating.

Removed everything for Mac and Linux--need to fix this later.

SpikeDetector used the channel count as eventType on the event channel list, which was used by SpikeDisplayNode to draw the appropiate plot. However, eventType should be used to differentiate different event types, as TTL vs. SPIKE. As result, SpikeDisplayNode tried to plot TTL event channels as 3 electrode plots.
Fixed by adding an offset (SPIKE_BASE_CODE=100) to the channel count at eventType to avoid said collision. However, we perhaps should try to find a more elegant solution.
