InfiniPaint vibrate on colorchange, fix color rotation

[clemensvonmolo]

This is a very simple pull requests that changes the Paint app in order to vibrate on color change (because It's hard to know if the touch controller actually registered a long press or a small swipe). I also fixed the logic for the color rotation. Before, the color magenta was unreachable and instead black was chosen a second time. The color variable was changed to initialize to 3 instead of 2, so you don't have to press twice on the first rotation.

• the changes were successfully tested on hardware and showed no problems.

Whoa, didn't even realise the colours could be changed!

Not super related to this PR but I would love to see a way to just set a system event for the motor instead of having to pass this around so much....Nice pr tho didn't know you could change the color.

A proper fix for the color would be to increment the color before the switch and modulo with 8. That way we use 0-7 instead of 1-8. Currently the color variable points to the next color instead of the current one which is strange.

The vibration is a good idea.

Maybe the vibration doesn't have to be so strong. 35 duration is usually used elsewhere.

Other than that this looks good.

The run duration seems a bit all over the place. (Currently 50, 90, 30, 35 and 15 are used.) Maybe a design guideline with times for strong/medium/weak vibration would help. For now I will change it to 35 since that really is the most common one.
