some cleanups
add these items in the roadmap as issues in the github tracker
need the DJANGO_SETTINGS_MODULE or else manage.py won't work. Need UTF-8 or else browsing mezzanine gallery won't work.
make setting the password configurable. need to warn user not to commit mkadmin.py to source control
no static or uploaded assets will appear without redefining these
if the requirements.txt file is already in the dir, don't do anything, otherwise make a requirements file that points to the one the user provides.
add a validator to make sure the requirements file exists. ask for an admin password.
