* re-organized imports according to pep8 * fixed all remaining pep8 issues * moved common config into setup.cfg, additionally test `tests` * removed --select=X -- the errors selected where by default not in flake8's --ignore list so effectively had no effect * update .travis.yml to reflect changes in tox.ini * make travis just use tox in order to avoid code duplaction * replace py.test with pytest * fixed .travis.yml * try different pypy toxenv * hopefully fixed testenv for pypy * added pypy basepython, removed unused python2.6 * install dev package before testing (fixes missing coverage) * fixed empty exception pass blocks with noqa * Added dummy log message on empty try-except-pass blocks to make dodacy happy :( * Replaced Exception with BaseException
