Classes for a timer and feedrate

Any thought about adding a timer to the run page, just to give us an idea of how long its been running.

And maybe a feedrate displayed that can change with the +/- 10%?


+1, a timer history is available on the laser I use and is quite helpful in determining what to charge for completed work.

The feedrate should update as one adjusts the feed in Grbl 1.1 and CM4.
