Debian packages for antimicro and mupen64plus

Program `antimicro` is packaged and available [in the PPA](https://launchpad.net/~beauman/+archive/ubuntu/retrorig/+packages) as version 2.5.20140905.0, where 2.5 stands for the latest [changelog entry from the upstream distribution](https://github.com/beaumanvienna/antimicro/blob/master/Changelog), 2014/09/05 is the date where I forked and baselined the upstream code into branch "retrorig-pl0", and ".0" is the patch level, meaning unpatched in this case.

The build script is not pulling any additional archives from any server, so this is a nice example for a minimum packaging effort.

While I was previously always using `native` as Debian package format I am now using `quilt` for the first time. I think this is why the [source shows up in the PPA](https://launchpad.net/~beauman/+archive/ubuntu/retrorig/+sourcepub/4394765/+listing-archive-extra). Much better, we should change all packages to this format.

I left a note on [https://github.com/Ryochan7/antimicro](https://github.com/Ryochan7/antimicro/issues/128) about the creation of the Ubuntu package.


This pull request closes #104 "Build script and Debian package for antimicro".
