How to create a custom hat
-------------------------------------------

 - Copy the desired image into content/plugins/embeds/hats
 - Create a text file with the same name as the image.
 - Put the sprite's x and y offset into the file separated by a single space and save.
 - A third optional value of "false" can added to prevent the image from flipping to match the player's facing
 - Open content/plugins/embeds/hats/config.txt (if it does not exist, create it) and  put the hat's name here.
 - Activate the plugin. The new hat will load as soon as you enter a new map

Animated sprites:
-------------------------------------------

 - Each frame needs to be in its own file. The frames should be name <HAT_NAME><FRAME>.png, eg. "hat1.png", "hat2.png", "hat3.png",etc.
 - Frames should be the same dimensions since they all use the same offset
 - Add two new values to the hat's file, frame count and fps
