fix(taBind, textAngular-sanitize): Corrected and enhanced formating comming from Word and OneNote

 - taBind: replaced <span style='...veritcal-align:super;...'>...</span> -> <sup style='...'>...</sup>
   so that we now see superscripts from OneNote
 - textAngular-sanitize: vertical-align is now accepted as a style adjustment
   and font-size is now enhanced to accept more of the standard settings.
