Extbase Hijax

Nested event listeners might fire unneeded amount of calls (one for each listener). If a listener and its child are listening to the same event which got fired both will get revived and rerun. The child listener of course won't be displayed, as the parent might render it again during its rendering process.

This seems unneeded from the rendering point of view (which is the main point of extbase_hijax). In some special occasions current behavior might be desired - so it would be good if this can be configured somehow.
