events TPL_ACTION_HTML & TPL_DISPLAY_HTML

event   TPL_ACTION_HTML
data    $ACT
action  tpl_content_core (formerly tpl_content)

This event is a wrapper for tpl_content() (now tpl_content_core()) and as such is a
full trigger, meaning it issues three advises:
- TPL_ACTION_HTML_before
- TPL_ACTION_HTML
- TPL_ACTION_HTML_after

Event handlers can output HTML before and/or after the main Dokuwiki page output and
can prevent the default dokuwiki page generation taking place.

Example uses could include:
- replacements for dokuwiki command handlers like index.
- appending a discussion section to the page by handling TPL_ACTION_HTML_after

event   TPL_DISPLAY_HTML
data    html output produced by tpl_content_core[1]
action  send output to browser

Event handlers can post process the HTML output before it is sent to the client
browser. This is a full trigger, meaning it issues three advises
- TPL_DISPLAY_HTML_before
- TPL_DISPLAY_HTML
- TPL_DISPLAY_HTML_after
