update ListView performance

the list view was taking long time to load when swipe for ex. takes 2-
seconds becuase of html2Text algorithim
before fix used html2text on update.setText() so for every loading will
call it
the fix is to save it parsed so when downloading /pushing
.download/refresh will save it parsed one time and the other time will
be shown parsed no dealing with strings
temporarly ...another algorithim in search !
