Last Update for Installed extensions

[disshishkov]

Currently Last Update sort option doesn't work for installed extension, because Brackets is not including update date into layout for Installed tab.
What do you thing about modify http://brackets-rating.herokuapp.com/ratings/ that it returns update date as well. I made some tests with timestamp but it's published date and we can not to use it.

mutation.js

....
forks = registryEntry ? registryEntry.forks : 'NA',
timestamp = registryEntry ? registryEntry.timestamp : '1970-01-01',
....

....
$t.attr('data-extension-forks', forks);
$t.attr('data-extension-timestamp', timestamp);
....

....
'update': function(elements){
      return _.sortBy(elements, function(el){
            return -new Date($(el).attr("data-extension-timestamp"));
       });
},
....
