 *
 * AJAXified Shoutbox module for TikiWiki 2.0 (jonnybradley for mpvolt Aug/Sept 2008)
 * 
 * Prefers Ajax enabled (Admin/Features/Experimental - feature_ajax) but will work the old way without it
 * Anonymous may need tiki_p_view_shoutbox and tiki_p_post_shoutbox setting (in Group admin)
 * Enable Admin/Wiki/Wiki Features/feature_antibot to prevent spam ("Anonymous editors must input anti-bot code")
 * 
 * Module parameters (with default values):
 * 
 * 	tooltip    = 1 (or 0)	put shout date in tooltip on user link
 *  buttontext = 'Post'
 *  waittext   = 'Please wait...'
 *  maxrows    = 5
 *  (plus all the usual ones: title, flip etc)
 * 
 * Example: tooltip=0&waittext=Hang on...&buttontext=Shout!
