Provide tabIndex prop to allow for sequential tabbing in forms

[haxxxton]

When quill is part of a form where previous/next inputs have tabindex > 0, sequential tabbing is lost, as elements of quill do not allow for tabIndex to be specified. It would be great if all elements generated by quill had their tabIndex explicitly set to a defined prop that defaulted to 0.

I think tabIndex support for the built-in editing area is a sensible request. I'm all for this being in the next release.

However, I can't see how the same could be done for the toolbar, without either providing a custom toolbar, or monkey patching the elements (which I won't do). I suggest pushing your proposal upstream to Quill itself.

In the meantime, you can accomplish both, in a slightly more verbose way, this by providing a custom editing area and a custom toolbar.

The new tabIndex prop unfortunately does not seem to work for me. The tabindex property doesn't seem to be applied to the div with the ql-editor class (which seems to still get focus through tabbing because it has contenteditable set to true).

I could provide a little PR for that although I guess that should be handled by Quill itself instead.
