Great refactor. Do you need some help here?

@AugustoAleGon definitely. But that would be after the refactor. I'll be adding some more comments in here. The plan as stated earlier in #31 is to reduce the number of props significantly, make styling configurable and also fix the most pressing issues.

During this refactor, some of the features would be removed until we figure out how best to re-add them back without having such a huge number of props. Below is the current type definition:

export interface MultiSelectProps {
    items: MultiSelectItem[];
    selectedItems: string[];
    onSelectedItemsChange: (selectedItems: string[]) => void;
    onAddItem?: (newItems: MultiSelectItem[]) => void;
    isSingleSelection?: boolean;
    hideSubmitButton?: boolean
    hideTags?: boolean;
}

It will most likely change before I wrap up the refactor in a couple of days.

I will make a list of all features removed during the refactor and we can split those up.

@toystars awesome looking good.
