Setup Launchpad daily builds

Launchpad can automatically create a .deb package from the repository. This package can be installed on Ubuntu distributions from a PPA. Launchpad will also run unit tests before making the package, to ensure that it is working. Having daily builds will make it much easier to install and test holopy.

To implement this blueprint, we will first need to create some packaging scripts. These can go directly in the current repository. Guidelines are here:
http://developer.ubuntu.com/packaging/html/packaging-new-software.html
and guidelines for packaging python packages are here
http://developer.ubuntu.com/packaging/html/python-packaging.html

Then we need to create a launchpad build recipe. The launchpad guide is here:

And a blog post with screencast describing the whole process is here:
