Virtual Scrolling for (Multi)Select Component

[Ri-gers]

Would it be possible to add a virtual scrolling mechanism to (Multi)Select similar to DataTable in order to improve performance drastically? For example, when having more than 1000 items in the list, scrolling through them becomes very slow and laggy. Using the search field helps to mitigate this, but you need to know the selectable item names in advance for it to be effective. Therefore, improving the performance for a large pool of SelectOptions would be preferable

Since the release of 2.0.4 drastically improved (Multi)Select performance, I think this is no longer really necessary since this could be a little overkill - close this if desired
