David - A Flask CMS with SQLAlchemy

The CMS behind http://www.tongdawei.cc

TODO:

1. more generic templates
2. more generic static files handling
3. provide modules as plugin

Decisions I made

1. make modules as pluggable as possible, see david/modules
2. implemented qiuniu CDN attachment upload and its Flask-admin interface
3. use Flask-babel for locale
4. use alembic for database schema versioning
5. use grunt to build static files
6. use fabric for deployment
