Issue description
It should be possible to define triggers (or event handlers?). Code should be held in a directory triggers next to the directories domain and services.Comment
Triggers are created on the command line with the new create-trigger command. This creates a topic of type Topincs trigger with id ID writes a file into STORE_DIR/php/triggers/ID.php. The user has to 1) specify when the trigger is run and 2) code what the trigger should do.
This looks very useful, whether you have streaming input or not.
