Calendar caption with renderCalendarCaption

[nezed]

An excerpt from README:

Optionally you can provide calendar caption block renderer.

   renderCalendarInfo: PropTypes.func,

Usage example:

  const CustomInfo = ({day, format}) => (
    <div>
      ❕ Some useful info here
    </div>
  );

  <SingleDatePickerWrapper
    renderCalendarInfo={() => (
      <CustomInfo />
    )}
  />

Example screenshot:

The renderCalendarInfo prop are universal, and available in DateRangePicker, SingleDatePicker and DayPicker.

As a part of #331

Hi! Sorry for the delay in review. :) This looks great! I have one small nit, and then some questions about the naming of the prop in general. I'd love to get this in ASAP though.

[majapw]

I'm concerned with the nomenclature of using caption here as we already have a <caption> dom element on each table inside each CalendarMonth component. I think using Calendar is also somewhat problematic as this is rendered on the DayPicker level not on the CalendarMonth level. Perhaps renaming it to renderDayPickerCaption or renderDayPickerAdditionalInfo might be a good idea? What do you think?

[majapw]

Oh this is totes my fault by having the Calendar props story isn't it. What if we called this renderCalendarAdditionalInfo or something? Maybe even just renderAdditionalInfo? God, I'm verbose.

@majapw Glad to see your response!
Maybe its better to this props renderCalendarInfo?

[majapw]

Yes. Let's do that instead!
