Revives the Word of the day plugin.

This is an old word of the day plugin from CloudBot2.7, I haven't tested this with Refresh, but it works on 2.7.

Seeing as I fixed this plugin for a friend I figured I'd send in a PR regardless.
It seems like `.renderContents()` is spitting out some weird encoded version of the information in the tags, as `b'noun'` and similar. I'm not sure if there are any issues with this, but changing the `.renderContents()` call to just `.string` seems to be working for me.
