Added fix to 1.5 branch. r13650

In the case where a user changes focus before the server focus call is executed, the server focus call is ignored. Focus is only moved if the user is not interacting with the browser. (Keypress, or mouse click)

A short delay prior to setting focus is unlikely to have any undesirable side effects (outside of focus behavior) as the delay wouldn't block anything else from occurring.

However, the delay may mean that there is a period of time where nothing is focused, yet the user is expecting some component to be focused. We should take care to ensure that rapid focus operations on the part of the user aren't interfered with by setting the focus later.

I had to add a slight delay to the focus call (100ms). IE 6 and 7 now focus properly.
