Change `js-quick-submit` behavior to expect the class on the form

Now it will work on any field inside that form, and it's easier to scope
new behavior, which is what we're adding next!

app/assets/javascripts/behaviors/quick_submit.js.coffee

 # Quick Submit behavior
 #
-# When an input field with the `js-quick-submit` class receives a "Meta+Enter"
-# (Mac) or "Ctrl+Enter" (Linux/Windows) key combination, its parent form is
-# submitted.
+# When a child field of a form with a `js-quick-submit` class receives a
+# "Meta+Enter" (Mac) or "Ctrl+Enter" (Linux/Windows) key combination, the form
+# is submitted.
 #
 #= require extensions/jquery
 #
 # ### Example Markup
 #
-#   <form action="/foo">
-#     <input type="text" class="js-quick-submit" />
-#     <textarea class="js-quick-submit"></textarea>
+#   <form action="/foo" class="js-quick-submit">
+#     <input type="text" />
+#     <textarea></textarea>
+#     <input type="submit" value="Submit" />
 #   </form>
