This reverts commit 17e7066.

major changes:
1) all py files were refactored in pep8 style
(except for 97 lines in utils.py)
2) splitting BaseBox into BaseBox and BaseBoxList for convenience
(with the corresponding estates of both the models themselves and the models inheriting these models)
3) added:
- get_brawlers function
- model Brawlers
- BRAWLERS_URL in API
- nothing function to replace lambda expressions in typecasted
4) changed async.py and sync.py (now they are completely identical, in terms of meaning)

.. add some of my files to gitignore

Issue 60 making get brawlers

- change back to testenv
- fix to load brawlers for async clients (tox doesnt work currently but should work for users)
