Reorganize source tree to have a "cubicweb" top-level package Basically: mkdir cubicweb hg mv *.py -X setup.py cubicweb hg mv dataimport devtools entities etwist ext hooks i18n misc schemas server skeleton sobjects test web wsgi cubicweb Other changes: * adjust path to cubicweb-ctl in devtools tests * update setup.py to avoid importing __pkginfo__ (exec it instead), replace os.path.walk by os.walk and prepend `modname` here and there * update tox.ini to account for new test locations * update doc/conf.py so that it still finds __pkginfo__.py and CWDIR in doc/Makefile
