Useful packages & other improvements

[ErisDS]

In the interest of trying to make Ghost-Vagrant the best possible way to dev for Ghost, there are a few packages that could be installed that would be great:

• sqlite3, so that it's easy to edit the DB
• nodemon (npm module) for watching the node app instead of just running it
• watchman (npm module)
• git-completion (apt module)
• git prompt (https://github.com/git/git/blob/8976500cbbb13270398d3b3e07a17b8cc7bff43f/contrib/completion/git-prompt.sh)

It would be amazing if we could forward .gitconfig from the client machine to the vagrant machine as well (some ideas how as the first thing I do after vagrant ssh is type git st and get an error 😉

Also the following package is no longer needed:

• casper.js

I also recommend having the service called ghost rather than app as that is what it's called pretty much everywhere else (DO setup, our init script, etc) and I always forget this.
