Add ability to filter options in Select component

[cgregs32]

It has been suggested on many occasions (for our use case) that we be able to filter the Select component by key input. For longer/ growing lists, it will allow users to be able to seach the options within the dropdown.

I think this would be a beneficial addition to this component, that can be used optionally.

It should be configured via a prop input on Select component - defaults to false.
