UI: List Template tweaks to get it a bit more usable

* Mouse wheel now scrolls the list.
* Up/down key and alt mouse wheel change the active item.
* Adding/removing items from the list now automatically scrolls so the
  active item is in the view.
* Shift mouse wheel changes the size of the list widget to display more
  items. Lazy replacement for a proper grip.

* Shape key list now displays the influence value next to the name,
* Also fix the range of the value slider to match the defined min/max
  range.
