#10 Chat list: handle embedded newlines

[Javier Kohen]

The chat list parser doesn't handle newlines embedded inside a tag. Room topics may contain these characters, which breaks the parsing.

Don't ask me how to set these topics, I haven't tried, but I've seen that happen.

The patch also fixes the handling of the > character inside attributes, which I've also seen happen in the same room tag as the newline issue (maybe a smart guy trying to crash some clients...)
