Date/Time: Use numeric input for touch_time() fields.

This aims to make it easier to enter digits in datetime text fields on mobile devices, instead of opening the full keyboard.

Follow-up to [43], [1506], [2998], [3648], [6078], [6989], [7285], [7338], [20168], [20217], [28730], [32945], [49283].

Props sabernhardt.
