Created TODO.
Altered command line arguments.

Martin Ortbauer improved the command line arguments in a fork. It's a lot
better than the flags I was using. My implementation is slightly different than
his in that you can still start/reattach to a session with 'tenper my-project'.

Longer left-status for long project names.
Added session-specific environment variables.

I'm adding this because of the way the Django sites are configured for some of
my work projects. I need to set the DJANGO_SETTINGS_MODULE per project.
Added a method of tab completion for zsh.
