core: split add_event() in two parts

Browse source 
add_event() creates and adds an event from the given parameters.
For undo, we want to do these separately, therefore split this
function in two parts: create_event() and add_event_to_dc().
Keep the add_event() function for convenience. Moreover, keep
the remember_event() call in there, so that undo-commands can
call remember_event() once, not on every undo/redo action.
