Added {first_letter} format

Alphabetical sorting for your model folder.

model_username = belledelphine

{first_letter} = B (Will always be capitalised)

Useful if you have thousands of models and you'd like some sort of pagination so your drive doesn't come to complete halt. Network drives have a huge benefit as well, such as a smaller cache and load.
