Add Urric's archvile

[Ferk]

This is the archvile created by Urric: https://www.doomworld.com/forum/topic/52718-my-archvile/

I've assembled his work and put together a small variation for the resurrection animation.
The attacks only have the front angle but it's still much better than the current archvile and since its attack doesn't really need aiming it still works well, imho.

Sweeeeeeet. Huge improvement and looks great.

Before I merge this in, could you please attach the email/message/whatever from Urric to confirm that he did allow this to be added to Freedoom?

[Ferk]

It's in the forum thread but I'll also quote him here.

This is the response he gave when asked to offer his work so we could work on it and include it in Freedoom:

Hi!

Here is my Archvile folder, the most important files are the photoshop ones, which are psd extension, whoever check those files is going to decipher how is sort of the psd files but i dont think that would be a trouble, i hope this help a lot the community, and of course i hope i get credit for my work.

Hmm.. the link is no longer working. Maybe he doesn't want too many people seeing his google drive folder.
But I asked beforehand permission to make public this response from him.

Thanks! This has been merged in.
