Track Device Utilization Over Multiple Compilations

[nanocyte]

I think it would be useful if LV kept track of device utilization over each compilation. The data could be presented as a graph which might give useful clues to the developer how the project is approaching the limits of the FPGA. Also, I think this data could optionally be stored in the same folder as the bit file so that the developer can review the file history with their source control.
