Added simple installer for the whole OS. Note that this installer depends on 'extlinux' which comes as 32-bit binary. The installer works fine but the dynamic libraries need better handling for 64-bit host machines. Most probably additional 32-bit 'glibc' build will be required in order to generate the proper libraries.
