Feed improvments fix the LCD garbling!

The sprockets have been replaced and improved with key ways cut into the jack shaft and auger.  This allows positive feeding without slippage.  The jack shaft placement was constrained so adjustment of the chains is limited to what linkages can be removed or replaced with half links and adding a slack tension device on the slack side of the roller chain.  With this complete the LCD problems appear to be fixed.  Without proper tension the chain did not ride on the sprockets smoothly and the tension could take up suddenly adding a jerk to the system.  Without this mechanical jerk in the system the motor can work more smoothly allowing the LCD to not get the power fluctuations that garble the display.  The feed problems appear to be fixed but in the last test the unit ran for four days without fail and at this point although there is a marked improvement that time has not been surpassed.  Next on the list is the hopper extension to allow feeding of two bags of pellets.  This will allow 16 hours of run time without any software improvements.
