Album Art Downloader 0.19

The Album Art Downloader is a simple, small and easy-to-use program that was designed to make life easier for anyone who wishes to find and update their album art for their music collection.
The sources for the pictures can be defined by creating plugin scripts.
A file browser and a foobar browser are included.

Enhancements:
- Search results grouping (by source, or by local / online results)
- File and Foobar browsers now support multiple alternates (separated by a "|") for image path searching
- Added the ability to the File Browser path pattern matching function to specify the path should match folders rather than files (by ending the pattern with ".")
- Delete key now removes items from history lists
- Changed Local Files Source settings so that a path is always set, but added new "%folder%" and "%filename%" placeholders to it, which produce the folder and filename of the specified default path to save images
- Improvements to the generation of the default filename to save to when launching from file and Foobar browsers
- File path pattern matching box history list fixed
- Some keyboard accessibility bugs fixed
