Truncated user list in award emoji tooltips

* 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
