+Summary: some control events are not fired (i.e. LoginStatus.LoggedOut) [w/ fix]
+When trying to hook into the LoggedOut event of the LoginStatus control, I
+noticed that the method that was registered via the ascx was never called.
+ I looked at the disassembled version of the generated class, and noticed
+it was trying to do a "SetAttribute" on an IAttributeAccessor, rather than
+trying to register for the event.
+I traced this down to the TemplateControlCompiler, and the section of code
+that deals with event registration appears a bit weak,  Previously, checked
+to see if the attribute name started with "on" to determine if it was an
+event registration.  Well, for the LoginStatus, the attribute is
+"LoggedOut", and not "OnLoggedOut", hence the event was not properly
+Honestly, am not sure what the proper fix is for this, but the following
+does fix the LoginStatus.LoggedOut registration, and should be generic
+enough to solve other cases.  It leaves the "on" check in place, though it
+seems that there should be a better way to handle that.
+Anyways, here is the patch that adds an extra check to see if the id is for
+an event, while leaving the existing check in place:
