 /* Convert Word Documents to HTML
 *
 *  Cleans up the otherwise-ugly output generated by Microsoft Word when you use the File -> Save As HTML option.
 *  and optionally includes Twitter Bootstrap. Relies heavily on WordPress's texturize engine and internal encoding
 *  functions to do the heavy lifting. Also converts footnotes into a format compatible with Bootstrap's tooltips
