Scaffolding scripts

[dchaplinsky]

We need a simple script that will be installed alongside with package and can create an empty project with file structure like that:
Procfile
app.py
local_settings.py
----probably (optionally?)---
heroku related stuff.
uwsgi related stuff.
.hgignore
.gitignore
plugins/demo_plugin.py

It should be described in docs as well.

Basically we need super simple analog of django-admin.py or scrapy.py so newcomers can easily start playing with the system.
