New helpfile/wiki article: Yru

[Rias]

There is now an article on Yru the Soulreaper! This can be viewed by typing HELP YRU in-game, or by clicking here to view it on the wiki.

Yru was a trickier one as I felt I had to get the "Soul" article out first to explain the difference between "soul" and "spirit". I also now need to write an article on the Hungering Night.
