QEmu (not working) & x86 support. Clean-ups and updates

NOTE: bin-npkg has been disabled due to permissions problems. It's not an issue to take a look around, but also ndm seems a better alternative
Using only minimal dynamic libraries and exec initramfs init file
Static node.js, cleaned libraries, init in Javascript
century working as /init on dynamically linked Node.js
Hardcoded generated files are real ones & Node.js automatically updated
Define packages in package.txt files and create disk image
Mount /dev, /proc & /home filesystems
Define user packages in packages.txt file
Clean-up and generation without root priviledges
Changed sudo permission building for Docker
Comments on package.txt and root user /init file
Use 'env' from compiled coreutils instead of host system one

Size is fairly bigger, maybe it has the debug symbols? We should remove them...
Compile Node.js from tarball instead of git repository

This allow faster downloads
forever-starter -> getty -> nsh
Generate Docker.io with new structure
Fixes for QEmu after adaption to Docker.io, now both works
Merge pull request #12 from piranna/master

QEmu support
