v0.3.0

• The code has been thoroughly refactored, and fully
  documented. Yay!
• Removed Flickr.api_methods – the consequences of its existence made the
  code uglier.
• Added #find_by and #filter to
  Flickr::Object::List.
• You can now access the raw JSON response of a Flickr object with
  #attributes.
• Increased the default timeouts, so now the HTTP requests shouldn't timeout on
  normal internet connections
