Changeset 580

Message:

• Image plugin:
  
  • Updated to generate and append thumbnails.
    
  • Refactored the calculation of the supported formats.
    
• MP3 plugin:
  
  • Modified to accept 'audio/mpg' and 'audio/mp3' as well as 'audio/mpeg'.
    
  • Added some diagnostic logging for album-art extraction
    
• Fixed a bug in the formupload handler's template when uploaded files don't have an associated
  title.
  
• Wrapped Rakefile tasklib loading in better diagnostics
  
• Renamed the 'rdoc' tasklib to 'docs' and moved the manual task to that library to eliminate the
  dependency on 'uv' for non-manual-related tasks.
  
• Added coverage to the spec for ThingFish::Request and made #check_body_ios check appended
  resource IOs as well as entity bodies.
  
• Added a 'bench' shortcut for 'benchmarks:all' to the benchmark tasklib
  
• Fixed a typo in ThingFish::Client API docs.
  
• Changed the way recursion works in ThingFish::Request#yield_each_resource -- no longer (needs)
  uses Enumerable::Enumerator, and eliminated newly-appended resources from sometimes being
  yielded back to the block. Thanks to Jeremiah Chase for pairing with me while tracking this
  down.
