Server installation

- Bring back and update several files to support installation via `install.py`
- Update `upstage-server` to kill all running process properly and remove `ant kill` and bring back `ant stop` 
- Update `upstage-admin` so when using the command `upstage-admin create` the admin use specified will own the default 'test' stage and all media assets
- Fix policy port problem

These changes mean the Server Installation manual does not need to be updated
