Subject: Refactor utility scripts


This patches introduces a new script `manager` and move the
functionalities of create_sqlite_db, start_freshmaker_from_here and
start_frontend_from_here to this new script.

During development, we need to set PYTHONPATH and
`FRESHMAKER_DEVELOPER_ENV` to run commands from `freshmaker/manage.py`,
the removed scripts only sets those two variables for limited commands,
not all. New script `manager` fixes this. That is useful for me
particularly to run commands related to database migrations as an
example.

Script manager accepts argument either help, -h, or --help to print
usage. Command `createdb` maps to `create_sqlite_db`, `runfrontend`
maps to `start_frontend_from_here`, and `runfreshmaker` maps to
`start_freshmaker_from_here`. In addition, all commands
`freshmaker/manage.py` accepts are usable as well, for example `manager
db revision --help`.
