CoffeeScript generated JavaScript contains some unreadable
expressions. This refactoring addresses complex uses of
the exestential operator that produced unreadable Javascript.

* resetTooltip totally destroyed and regenerated the
  tooltip while fixTitle simply replaces the text in
  the existing element.

* resetTooltip also called an asyncronous function
  with no suitable callback resulting in a messy
  setTimout workaround. fixTitle is syncronous.

* Works by explicitly deleting out-of-date data attributes

* No longer directly assigns to data-original-title

* Code in ruby now uses Array#to_sentence to construct award tooltips

* Coffeescript uses a combination of regexes for the same result

* Only the first 10 names are displayed

* Further users are indicated by "and X more."

* String "and X more" is appended to the array THEN join is called

* An oxford comma seperates the last name from "and X more"

* In coffeescript "me" is now always prepended

* Tests included
