picorb floppy

I've just created a bootable floppy of which 400K is used, which can be used to demonstrate picorb. GRUB by itself takes 152K on the FAT-formatted disk. eCos and the demo CORBA server implementation take 255K of which eCos takes about 240K. For now, I've taken a basic configuration of eCos, which I intend to strip down. The demo server implements a CORBA object supporting an interface containing 21 methods.
