Extend control

Hello, we are using your plugin to build some of our rpms and debs and we like it a lot.

I have realized that in Ubuntu, when I double click on a .deb file that's been generated by the plugin, the package manager alerts the user that the software he is trying to install, is not reliable, just because it doesn't fill the Installed-Size parameter in the control file.

I have fixed that, and I thought you could include some of it in your code (or even create a new branch so that we can include images for the deb's instalator icon, such as a screenshot , etc).
Thank you
