The events listener now uses a proper self-consuming queue and the event handlers have been rewritten accordingly. The way this works is that running init() on the handlers library instantiates the handlers and returns two higher-order functions, prepare() and despatch(). A call to the latter of these is appended to the queue with each new incoming event. The handlers have access to a context object (ctx) which may be used to persist data between calls and/or exchange data between handlers. This is used notably to give the handlers access to project configurations, which are themselves refreshed by a project configuration change handler (DetectProjectConfigurationChange).
