Add a button for end of drying phase about artisan HOT 4 CLOSED

I reopened the issue as feature request as it makes sense to me to have a mean 
to manually overwrite the default drying phase limit if one can clearly 
indicate this event during the roast. With this feature the statistics (based 
also on this event) are more accurate. 

A workaround using the current implementation would be to add an "extra" event 
via the EVENT button on discovering EndOfDry and manually adjust the phases 
settings for this profile accordingly after the roast.
More cumbersome but should work now.

I was wondering about the possibility of inserting an extra button between 
"Charge" and "1C Start" called "Drying End" or something similar

added new button to mark the end point of the Dry phase
