minTime and maxTime not displaying when minute = 0

[MrMacvos]

There's a small bug in 0.3.3 inside the selectHours function:

        if (onMinuteShow || maxTime.minute || minTime.minute ) {

should be:

        if (onMinuteShow || maxTime.minute !== null || minTime.minute !== null) {

to get it working with the 0 minute: maxTime:{hour:18,minute:0}
