 * Makes a post in the specified forum, in the specified topic according to the given specifications. If the topic doesn't exist, it is created along with a spacer-post.
 * Spacer posts exist in order to allow staff to delete the first true post in a topic. Without spacers, this would not be possible with most forum systems. They also serve to provide meta information on the topic that cannot be encoded in the title (such as a link to the content being commented upon).
 *
 * @param  object			Link to the real forum driver
 * @param  SHORT_TEXT	The forum name
 * @param  SHORT_TEXT	The topic identifier (usually <content-type>_<content-id>)
 * @param  MEMBER			The member ID
 * @param  LONG_TEXT		The post title
 * @param  LONG_TEXT		The post content in Comcode format
 * @param  string			The topic title; must be same as content title if this is for a comment topic
 * @param  string			This is put together with the topic identifier to make a more-human-readable topic title or topic description (hopefully the latter and a $content_title title, but only if the forum supports descriptions)
 * @param  ?URLPATH		URL to the content (NULL: do not make spacer post)
 * @param  ?TIME			The post time (NULL: use current time)
 * @param  ?IP				The post IP address (NULL: use current members IP address)
 * @param  ?BINARY		Whether the post is validated (NULL: unknown, find whether it needs to be marked unvalidated initially). This only works with the OCF driver.
 * @param  ?BINARY		Whether the topic is validated (NULL: unknown, find whether it needs to be marked unvalidated initially). This only works with the OCF driver.
 * @param  boolean		Whether to skip post checks
 * @param  SHORT_TEXT	The name of the poster
 * @param  ?AUTO_LINK	ID of post being replied to (NULL: N/A)
