[ticket/15214] Add event & functionality for assigning template event priority

Browse Source 
Event added to allow template events to be assigned priority per extension,
event location chosen so that it only fires once.
Twig node event class refactored to allow template event priority assignment,
compile calls are deferred until all locations are processed
per extension namespace.
Priority precedence mirrors Symfony priority, with higher numbers
being placed at the beginning of the array.
Duplicate priority assignment will currently have the later events
compiled before the others.
