Various fixes in RSS feed generation

- Prevent `.xml` generation for root section
- Remove redundant check for DisableRSS
- Fix permalinks for rel="alternate"
- Rename generated xml file to <type>/index.xml
- Add required description element in default template
- Make default RSS template validate on w3c (timezone format is still an issue)
