Added dateStart and dateEnd for the calendar date range set. Fix #4801

### Steps to reproduce the issue

For now, it is not possible to set Min date and Max date for Calendar control so as to define range of dates.

### Expected result

##### Something like
minDate="16-10-2014" AND maxDate="16-10-2015"

### Actual result

Both Attributes are missing.

### System information (as much as possible)

### Additional comments

See #4801
@kirapwn can you add spaces so the `=` among each other?
