[Wbo2] simple warning LED display

[bcroe at juno.com]

My LED bar graph display for the DIY-WB does what you want.  
Except it tells you HOW lean it is, by the length of the red 
LED bar.  It does the same for rich, with a green bar.  Leave 
out the extra LEDS for less info.  A single LED would be 
like an idiot light for temperature; it isn't nearly as useful 
as a temperature gauge.
