1.0 = the REAL DEAL?

It's unused, declared obsolete, and is triggering GCC warnings. If
anyone wants it back, it'll be in the Git history.

updated the project build configs to include the SpikePlot.cpp and .h files and exclude the previous plotters

The IntanThread can report TTL events on its 6 input channels. This was tested
with an Arduino; input detection is fast and reliable.

The IntanThread also generates its own timestamps, allowing the software to move
toward a framework in which timestamps come from input sources, rather than
from the RecordNode.

Finally, an ArduinoOutput module was added, which allows the software to
communicate with an Arduino via serial output.

Channel selection now takes place within a slick new interface. It's not
yet tied to actually changing parameters, but things should be much simpler
code-wise, as well as visually.

UIComponent, ProcessorGraph, etc. were still referencing the configuration
class (but not using it). Those references have now been removed, as the
configuration object will be replaced by a set of parameter and channel
objects.

The waveform icons should be made a bit thicker, but otherwise these look cool.

If continuous channels are toggled for recording within their respective editors,
a "writeContinuousBuffer" function will be activated within the RecordNode. This
function doesn't do anything yet, but it will make it easy to add diskwriting
capabilities in the near future. Once a stable format for events has been established,
a similar function will be implemented for writing event buffers to disk.

A preliminary version of the ProjectionAxes that renders projection points using a texture instead of drawing each point. This should allow the plots to translate around the page without problem.  Additionally the plot can be flagged to regenerate the texture from scratch using a circular buffer of accumulated amplitudes. This hasn't been tested yet.  Additionally this code is very alpha and needs to be cleaned up and could break at any time.

Started integrating the TetrodePlot class. Oddly the projection plots aren't working although they were working in the stereotrode class, I'll have to figure that one out
