"Better" general purpose image thumbnails. Uses no filtering (crisp pixel art preview).

Pre-requirements:

1. Imagemagic must be installed and convert should be available from the PATH.

Installation:

1. Place images.thumbnailer to ~/.local/share/thumbnailers/images.thumbnailer
2. Delete all old thumbs: rm -r ~/.cache/thumbnails
