Feature: aa-charlink integration

[digital-pet]

Instructions below:

From version 1.1.0, CharLink supports hook integration. If you want to integrate your app with CharLink, you need to register a hook in the auth_hooks.py file:

@hooks.register('charlink')
def register_charlink_hook():
   return 'testauth.testapp.charlink_hook'

The hook has to return a string with the import path of the module containing the app integration. The module must contain a variable called app_import which is an instance of charlink.app_imports.utils.AppImport. You can find the documentation of the class in the utils.py and some examples in the imports folder.
