This patch adds the ability to run SingletonEventManager handlers in different modes: sync, async, raw (no exception handling, arg cloning, or asynchrony), or asyncWithoutClone. When you call the handler, you're required to specify which variant you want. Existing uses of SingletonEventManager are all converted to async calls. Note that some of them were previously synchronous, but it didn't appear to be necessary. Also added a callOnClose for SingletonEventManager when the last listener is removed.
