Added optional parameters minValue and maxValue

I added optional parameters 'minValue' and 'maxValue' for a time.
If an out of range time is selected, a message appears with the correct
range.
Ex.
~~~
$('#inputTextTime').timepicker({
minuteStep: 10
, showSeconds: false
, showMeridian: true
, template: 'dropdown'
, minValue: { hour: 9, minute: 25, second: 40 , format: '24h'}
, maxValue: { hour: 3,  minute: 42, format: 'PM'}
});
~~~
