Timepicker could add `inputmode="decimal"` attribute

[coliff]

Currently:

<input type="text" maxlength="2" class="form-control text-center bs-timepicker-field" placeholder="MM" aria-label="minutes">

UI would be better for users with virtual keyboards (touchscreen tablets/iPhone/Android etc) with:

<input type="text" maxlength="2" inputmode="decimal" class="form-control text-center bs-timepicker-field" placeholder="MM" aria-label="minutes">
