Add tooltip for bits in programming mode

For slightly more dyslectic people having to count out the bits is quite difficult. The lower labels help a little, but not enough. Further more, adding labels for all the bits just becomes noisy, ugly and also hard to read.

Instead, simply enable tooltips for all digits, so we can see what bit relates to what bit number.

Note, that the labels and id's are counting in the opposite direction as what where expected!
