	void bbc_to_html()

	void html_to_bbc()
		// !!

	void theme_postbox(string message)
		- for compatibility - passes right through to the template_control_richedit function.

		// !!

	void create_control_verification(&array suggestOptions)
		// !!

	void fetchTagAttributes()
		// !!

	array getMessageIcons(int board_id)
	- retrieves a list of message icons.
	- based on the settings, the array will either contain a list of default
	  message icons or a list of custom message icons retrieved from the
	  database.
