EWeb 0.52

The disk cache keeps pictures from more sites: a picture whose server says it varies by Origin or Cache-Control, headers EWeb never sends, was never kept, so iamexpat.de's pictures came again from the Pi on every visit; now a second visit takes them from the disk. Settings > General > Disk cache takes up to 512 MB (three digits; 64 until now). Options > Write a log turns EWEB.LOG on and off, as in ECal and EContact.
