Added a tag-team field to dungeons. This checkbox determines if the total players are played at once by multiple players, or by one player using tag-team rules.
Begun work on the Player. Currently have the "session" record created. Session currently holds the user's dungeon and current floor. Soon will hold player status and monster status, making it a full "Game Save"
Added the monster_instance and player_instance columns, and all of the player sprites.
Player_instances have an @images to list all of the images in the directory. This is also used to show all the player characters. As such, some characters that aren't actual playable (like wolf-karin) have been moved into the tokens directory.
