SmartClient 6.0 - Focus and scroll into view on cancelEditing

[Isomorphic]

In SmartClient 6.0, whenever ListGrid editing is dismissed via a call to cancelEditing() the ListGrid is given focus and scrolled into view.
This behavior is essentially a bug - there is no reason to put focus into the ListGrid body and scroll it into view unless the grid (or editors showing within the grid) had focus before the method was called.

This patch corrects this issue.
Note that as of the next SmartClient release (6.1) this patch will no longer be necessary and can and should be removed

//----------------------------------------------------------------------------
// Isomorphic SmartClient 6.0 patch
// Purpose: On cancelEditing() don't focus in the ListGrid body, scrolling it into view,
// if focus was elsewhere on the page
// 
// Applies to SmartClient 6.0 builds only
