ListGrid Extension: Scroll to a specified position directly after fetching data

[renzland]

Please see thread http://forums.smartclient.com/showthread.php?t=6349:

invalidateCache() is telling the grid that a totally unrelated dataset is being loaded and hence it should scroll to the top

This behavior should be extended, so it should be possible to scroll to a specified position directly after fetching data.

All doable, but requires ResultSet APIs that don't appear in SmartGWT yet (they are a top priority addition).
