Percent-encode '#' characters in irc: URIs

This is required to make the URIs syntactically valid; the channel
name is not a fragment identifier.

These aren't X[HT]ML documents, so xmlns:dct isn't a valid attribute.
The current RDFa Core specification [0] recommends the use of the
prefix attribute [1], so let's do that instead.
