fixed a couple of bugs in CheckConfig UI.  Now Groups can be ordered and saved in that new order.  Now the Save button is disabled while the page reloads after a Re-Order operation so that Save can't be clicked before the page has reloaded.
+ Changed ScriptManager.RegisterStartupScript() so it doesn't get called on PostBacks for the Checkin Config Controls.  The script would get added several times to the page otherwise. (this might be an issue in several other of our controls as well)
