Robo-Tank v6.6 is Ready

[gandalf]

Hi Gandalf, yeah it's coming for sure just not sure when, been really busy lately. Every now and then I put a few hours in. I'm working on the heater system and plan to release when that's finished.

thank you.
if you can, for the upcoming release, please add something that allow to customize a dosing "group", currently I have to change 24 dosing for each pump (i dose something hourly across the day). Even a delete-all would be ok, i delete the full group and i create a new from scratch if changing it is too difficult.

(as workaround i delete everything from phpmyadmin, but that's not good, and also needs a cotnroller restart)
