Start working on the installer script
Add password authentication
Make `lamassu` a SUPERUSER
Strip components
Install `git`

Quite a few packages in `npm` depend on things in git, make sure we're
able to install them.
Install `libpq-dev`
Fix `bin` in `package.json`
Bump version to 0.1.2
Install `build-essential` on Ubuntu
Drop user and database before creating them
Allow user `lamassu` to login
Correct Upstart service file name

Set `DATABASE_URL` in upstart services.
Use hex instead of Base64 for a password due to some URL-unsafe
characters in Base64.
Make `app.js` a proper executable
Bump version to 0.1.3
Change working directory to package's root

Otherwise SocketStream throws:

@floating is there any way around this?
Update the system before installing our software
Silence non-existent user and DB drops
Make output friendlier

Redirect output from commands to `lamassu-debug.log`, be a little bit
verbose about actions.
Shorten error handling a bit
Clean debug log
