Subject: [PATCH] Bringing the presentation of boolean variables (favorited,
 truncated, profile_background_tile) and the result from friendships/exist in
 JSON results from the Twitter Compatible API in line with what the real
 Twitter API does.

Currently, laconica returns text strings enclosed in quotes instead of bare Javascript booleans.  This change fixes that.

See http://laconi.ca/trac/ticket/1326 for one open issue related to this.
