Subject: tag-related fixes

1. move tag sanitization to feedparser common item class
2. enforce length limit on tags when parsing
3. support multiple tags passed via one dc:subject and other such elements, parse them as a comma-separated list
4. sort resulting tag list to prevent different order between feed updates
5. remove some duplicate code related to tag validation
6. allow + symbol in tags
