Added the ability to select items using arrow keys

Fixes #37 .

You may want to look at VueBootstrapTypeaheadList.vue's setActiveItem method, since it's perhaps not the cleanest solution.

@lisandromc your tests have failed, did you see why?

In some contexts, $listeners.keydown will be undefined and that breaks the component.
I have a fix for this, but I belatedly noticed that my PR should be done in the Development branch (duh!).
I will replace this with a proper PR as soon as I have some spare time.

Hi! I have just installed vue-boostrap-typeahead package and I notice that keyboard navigation is still not working. Do you have any news on this? Thanks

[mattzollinhofer]

This is the exact reason I wanted to revive (but ended up having to fork: https://github.com/mattzollinhofer/vue-typeahead-bootstrap) this repository. I really wanted a more accessible tool to use and I saw this (and other) PRs that had already been submitted to solve the problem!

To that end, I merged in functionality that I think meets this need here: mattzollinhofer@6646027. This implementation is mildly different but I believe the outcome is essentially the same.

Thanks again and chime in here or on the fork if you have any other thoughts! 😄

You can find the functionality on npm here: https://www.npmjs.com/package/vue-typeahead-bootstrap.

Cool, thank you!
