Adding sunrise-commander

The Sunrise Commmander is an double-pane file manager for Emacs

I am not package owner nor maintainer. I just like th package :)
This is just one file from that repository. It is packaged as intended by the author as you can see here: 
http://joseito.republika.pl/sunrise-commander/
Rest of the files in the repo are extensions in seperate packages
