Add post installation and pre removal script for debian package.

[fudanchii]

Current debian package wont stop droned when uninstalled.
Add maintainer script to do this.
Also auto-start droned when installed from deb, safe assuming that other real web server may already occupy port 80, set 8080 as default port to listen to.

Hey @bradrydzewski
should I update the README for this? or maybe you want to keep using port 80 as default?
It's actually fine by me, just want to play safe here. ;)

@fudanchii another awesome patch! thanks!

Let's keep port :80 as the default for upstart. I'm guessing that most developers downloading and installing with the .deb file will probably run on :80. But if it turns out they prefer :8080 then we can change it back :)

Thanks again!

[fudanchii]

Sure, sounds great to me.
I updated the commit.

Thanks!

Putting it on port 80 is what made me uninstall it a couple of weeks ago.
A mention in the docs how to change it would be nice I guess.

Also, I think most people running linux / a server will already have apache / nginx whatever running on port 80, using a different port is (IMO) the way to go.

Just my 2 cents ;)

You can change it in /etc/defaults/drone, an example is provided
