e07f818915
Adds a simple util function for firing a CustomEvent without detail and composed:true,bubbles:true. Replaces all dispatchEvent() calls with this util. Does not replace, if a detail is used of composed/bubbles are set differently. Does not add event type enum values, but just uses strings. Change-Id: I3148f4bfab5696f92320d22372ce215b61174256
