Fix #81: could not get paragraphs in Markdown due to the interaction between smiley and Markdown. Refactored the smilify code to use a series of regular expressions over the text when working with markdown.

.panel_wrapper {height:85px;}
.panel_wrapper div.current {height:85px;}

/* IE */
* html .panel_wrapper {height:100px;}
* html .panel_wrapper div.current {height:100px;}
