[v2.x] Hover callback, activeStartDate internal override...

[Christopher2K]

Hi !

I don't know If you still maintain the v2 but for my own needs, I had to implement some features:

• the ability to programatically control the date hovered
• disable the fact that when you specify a date not shown on the current view, the calendar will render the view where this specific date is visible.

It allow me to do things like that...

Hi, thanks for your input. I definitely like parts of this PR - like onMouseOut/onMouseOver thing for tiles. I think I'm gonna port this in. keepUsingActiveStartDate makes the whole idea of activeStartDate even more confusing, hence the changes in React-Calendar 3.0.

Hi ! Thank you for your feedback. I'll check changes in 3.0
