Added Collaborations Folder

It has come to my attention that you can collaborate with other artists on deviantART using Muro. More specifically you can color lineart in Muro and with proper credit can submit such works onto deviantART. There is even a group for artists that just like to color lineart known as color-me-club. Well I can't deny such artists so for the time being I have accommodated them with the Collaborations folder. As always categorization is left up to me, just please indicate in the deviation that it is a collaboration or colored lineart.

Thank you.
