Creatures and Deities Pages Updated

[muses_realm]

The Mythological Creatures page has a few new and tweaked entries and many new pictures. I also attempted a small spelling and grammar check while I was updating the codes, but I still may have missed somethings. If you notice anything amiss, please let me know so I can fix it.

The Deities Page has also seen some tweaks and additions, mainly in the Norse and Egyptian areas.

I've also added a Bibliography for the Deities Page as a whole.
