Reflectance & PSoC5

Changed the project to use the PSoC5LP FreeSoC Explorer board from the
PSoC Pioneer. This was mainly done to allow for software development
using FreeRTOS & to provide extra room for expanded sensors.  The LED
drive pin was moved from A4 to D2 to test the sensor array, but that has
little effect when the array is plugged in backwards.  doh!. all is
better with the sensor plugged in the proper orientation,
