Traceability for easy triggers

[xpdota]

Adds "sourceEasyTrigger" to the parameters for callouts from easy triggers, the value of which is the actual EasyTrigger instance that caused the callout.

Also adds a right click -> go to easy trigger option for callout events.

Example of how you can use a script to map up easy trigger callouts to their easy trigger names:

rawEventStorage.getEventsOfType(ProcessedCalloutEvent).collectEntries {
	def vars = it.parent.arguments
	def source = vars['sourceEasyTrigger']
	if (source == null) {
		return []
	}
	else {
		return ["${source.name}": "${it.ttsText}"]
	}
}

Once this branch successfully builds, you will be able to try the branch out for yourself by changing the "branch" in your updater to "easy-trigger-tracking" (without the quotes).
This setting can be found under the "Updates" tab.

Don't forget to change back when you are done testing. You should reset your branch either to 'stable' for normal releases, or 'master' for beta builds.
