nvidiabar, etc (#215)

* First experiment with $nvidiabar

Added nvidiabar, nvidiagraph and nvidiagauge. Using a dummy value of 50% for now until it is integrated with the nvidia value query functions.

* Implement get_nvidia_barval()

`get_nvidia_barval()` no longer returns a dummy "50%" but instead an actual value for supported arguments:

`gpuutil`, `memutil`, `membwutil`, `videoutil`,`pcieutil`, `fanlevel` and `gputemp`
