Added support of the JavaScript Engine Switcher version 3.0.0 Beta and JSPool version 3.1.0 Beta 1

Hello!

JavaScript Engine Switcher version 3.X has moved to the stabilization phase. I think that it's time to release beta version of the ReactJS.NET.

Main changes you can find in the “How to upgrade applications to version 3.X” section of documentation.

I removed the WrapJavaScriptRuntimeException method, because it was no longer necessary. JavaScript Engine Switcher version 3.X now provides information about error location in the message:

Thanks!! This might also be a good time to remove the references to Vroom, Chakra, etc from React.Core, and have users register their own JS engines.

Hello, Dustin!

Good idea, but it is better to implement it in a separate PR.

This looks pretty good to me! @dustinsoftware, what do you think? Any other changes we should make, or should we merge it?

[dustinsoftware]

Seems reasonable to me, let's merge and get a beta shipped

Shipped in 4.0-beta1 :)
