fix handleBeforeInput on v3 of draft plugins editor;

[elbakerino]

This fixed the setEditorState is not a function bug for my setup.

In the plugins editor the handleBeforeInput changed, eventTimeStamp was added.
https://github.com/draft-js-plugins/draft-js-plugins/blob/93f9d32b703cf8e65e3576a5803388b362d19ba5/draft-js-plugins-editor/src/index.d.ts#L65

Updated dependencies and especially the draft-js-plugins-editor and added the property eventTimeStamp in the index.js

Not really sure if this was everything.

Tested in an app with multiple editors on the same page and different draft js plugins.

Versions of the app tested:

• react 16.10
• draft-js 0.11.2
• draft-js-plugins-editor 3.0.0

That's why the dependency version range is tightened, as e.g. draft-js-plugins-editor 3 needs React 16.3 as minimum.

As temporary fix I published the changes as draft-js-md-keyboard-plugin

Would be great if someone checks it also and I hope this help!
