CYB-367 - Keep track of the current scroll position when going back to the gallery

CYB-367 - Further debugging

CYB-340 Comment on own gallery item should NOT score points for giving or receiving

* Comparison was being made between different data types; the poster's id on the parent
   item was an integer (Fixnum) but the current_user.canvas_id was a String.
  Calling '#to_s' on both, if later current_user.canvas_id is refactored to return an Integer,
   this will make sure that even if this code is missed, it will still work correctly.  #to_s
   on a String just returns self.

CYB-375 The date is no longer returned in the /gallery/index feed

 * adding the 3 date fields that are taken from the Canvas API return values
   for each asset type to the selected values returned

CYB-377 Youtube URLs are not always https

* changed the regular expression where it matched the protocol to always match
    http:// or https://
* This will ensure that Youtube videos are handled as such.
