Added cache

This will decrease the amount of CPU and RAM needed when generating fusions, but will use more disk space since we store each fusion as a PNG.

Check the changes in this commit for more information on how caching works.

# This directory is used to cache fusion as PNG files
# This way, they are only generated once, saving CPU and RAM on the server, at the expense of disk space
# Remember to delete the corresponding fusions in this directory if you make any change to an image in the /ponies directory, otherwise the changes won't be reflected
