What steps will reproduce the problem?
1. A feed has an icon that is downloaded for display
2. Remove the feed from the list in config dialog
3. Cached icon file is not automatically removed

Solution:

In save_dialog function:

Delete all png/gif/jpg icon files in cache? (icons of existing feeds downloaded on
refresh anyway)
- or -
Go through list of the previous feeds, compare with new list, check for removed feeds
and delete respective icons?
