v2.1.1: Timely™

• Log errors in both the command line and the error log window
• Rework meta-editor
• Ameliorate Gtk-WARNING messages (will be fixed in a newer Racket version than v6.7)
• Edit xmp:Rating from main window (with super cool Unicode shining stars)
  • xmp:Rating indicates its hierarchy based on its peers
  • 0 (the default) means the image has not yet been rated
  • -1 means the image should be ignored in rankings
  • 1 (the worst rated) - 5 (the best rated) determine the image's ranking
• Sort the current image collection alphabetically (default) or by xmp:Rating
  • May sort by highest rating or lowest rating
  • Sorting by rating in collections that contain many images may take a long time
• Center the frame and resize the frame based on the image's dimensions
  • The centering and resizing only occur on start
  • Calling Ivy without specifying an image will spawn the window in the center of the screen at its usual size

This update is necessary because it is built against the latest png-image that ensures the compressed text chunks inside a PNG are properly formatted. Before this change, pngfix would enter the deflated data directly, without adding the zlib header information or the ADLER32 checksum at the end.
