event SEND_HEADERS

Event data an array of headers dokuwiki will send[1].
The default action is to output all the headers in order using the header() function.

- SEND_HEADERS_before
- SEND_HEADERS
- SEND_HEADERS_after

Handlers of this event can add/modify/delete the headers in the event data. The event
data must remain an array, even if emptied.
