Custom Types

[AkeemAllen]

As a Rom Hack creator, I want to be able to document custom types for my Rom Hack.

• [x] Store types in json file
• [x] Link types to type images
• [x] Allow user to create new types and upload a sprite to represent it.
• [x] Allow custom types on moves as well

Allow for type images to be edited in a future update
