Fixed documentation links and updated the Studio Ghibli API endpoint.

New update!

• Fixes #30 (hmtai API was never down)

Updates:

• Added a new wrapper for the Catboys API (https://catboys.com/api).
• Updated the endpoint that the Nekos API wrapper uses by default. Nekos API has many endpoints (which all work), but since nekos.nekidev.com is deprecated it was changed to https://api.nekosapi.com/v1.
• Added a down message in the main readme for Animu API since it is down and was now moved to waifu.it. Since the documentation is still missing I'll wait until the official docs get released before updating the endpoint.
• Finally a stable version. After lots of 0.X.X versions, 1.0.0 is here.

TODOs for upcoming versions:

• Add a Nekos API v2 wrapper.
• Add more API wrappers.

Added new character metadata to Character object in Nekos API wrapper.

Updates:

• Added get_characters() method to the Nekos API wrapper (NekosAPI).

Added the new NekosAPI.get_artists() method for the /artist endpoint in the Nekos API wrapper.

This version brings a few updates:

1. The official Nekos API wrapper has been added
   Now you can access the API in a much more easy way! Rate limit handling is included, so don't worry about making too many requests. It is still missing great part of the documentation, but it's being worked on and will be complete in no time.

2. Hmtai wrapper is deprecated
   Hmtai was taken down and therefore the wrapper is no longer supported. It will continue being there by now, but it won't receive any new updates.

• Added Waifu.im API wrapper
• Added error checking function in AnimeChan API wrapper

• Fixed API search pagination limits for Nekos.best API wrapper

Added support for the Nekos.best API
