Accessibility : Initial Focus should be set to to Tabs when Table Properties dialog is opened

[Satya Minnekanti]

To reproduce the defect:

1. Open Ajax sample.

2. Go to the Tool bar by pressing Alt + F10 and navigate to Table icon and press Enter.

Expected Result:

Focus should go to Tabs first, User can navigate the Tabs using Arrow keys, and he can select the Tab that he wants by pressing Enter or space bar. when the user presses enter focus should go to first element in the Tab.

Actual Result:

Focus is going in to the elements on Table properties Tab directly when we open Table dialog.

To add to the description, the editor is loaded with config.dialog_startupFocusTab = true;
