TAStudio work:

-Fixed InputRoll.VisibleRows property.
-Removed useless check for NeedsScrollbar.
-Removed TAStudio.ListView.cs property for hiding lag frames; changed InputRoll.cs to do that work more efficiently.
-Feature: User can now edit float values by holding the mouse button and dragging up/down.
-Bugfix: Moving the cursor past first displayed row while painting would not cause first displayed row to be painted. (and similarly with last)
