option to not prevent key events

[magalhas]

Related to #110. Created a new prop to enable/disable keyDown default prevention. In my case having it as false works great so when a user tabs the field gets populated with the first visible option and it jumps right to the next field.

This seems to be named awkwardly. The name suggests that setting it to true will prevent key events. Perhaps this should be renamed to propagateKeyEvents and default to false? Then the code in _onKeyDown would be

  if (!this.props.propagateKeyEvents) {
    event.preventDefault();
  }

Otherwise looks good.

How about merge ?

[magalhas]

That would be awesome. Nothing against changing the name of the property.

I would really like to be able to use this feature. Any chance of getting it merged?

If we are waiting until we can get an update on the naming convention, I could submit an update to the naming convention.

@arahansen I'll pick this up if someone sends me a PR with an updated README.md and a unittest.
