Resolved conflicts in __init__.py and managers.py

* Much of the documentation doesn't match the code; code will be
updated in develop soon

* Support for starting commands using the bot's name
* Moved _wrap_check and _wrap_process to the CommandManager
* Removed extra sortkey in afc_statistics

- Category.members() -> Category.get_members()
- Category.get_members() now fully abides by the limit, which defaults
to None for SQL and 50 for the API.
- Category.get_members() always returns unicode objects instead of
strings for page titles.
- afc_statistics: Fixed a frustrating Unicode bug.
