Fixing rss.php

[Lucas-C]

The current RSS feed is simply broken, due to an extraneaous space in the XML version declaration.

This commit aims to:

• fix this
• properly order the images in the RSS feed by their timestamp
• add a pubDate entry to each item in the feed

The result can be seen here: https://chezsoi.org/lucas/wwcb/rss.php
