This adjusts how triggers are implemented during a normal run. Any defined triggers which are applicable are located and injected into the run stack as the stack is built, including hook type triggers. Support is included for dynamic hook lookup. The data type used when defining triggers has also been relaxed to support symbols, strings, or constants.
