Improve duration picker

[kylecorry31]

It should be like a timer app where you always enter digits to the right and they push over to the minute or hour field.

It should support all the following, but any can be disabled:

• Hours

• Minutes

• Seconds

• Pressing delete will remove the rightmost digit

• Long pressing delete will clear the field

• Maximum will be 99h 99m 99s, but a hint/error can be shown if it will be truncated on OK

• It should use the same style number pad as is in the timer app, or show the keyboard and capture events if possible (clicking the time will re-open it)
