Stepping back to fogging from the button

I took the code back to the point that the fogger goes off every time
the button is pushed. I didn't remove any code, just commented it out. 

The previous code was working great for one day and when I opened this morning the table was fogging every 45-60 seconds. So, upon Doug's request, I reverted back to the original code where the fog is produced every time the button is pushed with a one second duration time for the fog.
