Kernel: A lot of changes, please expand the the message.

Meta: Add eclipse project.

PowerPC: WiP implementation of a 64-bit PowerPC kernel, see specs.
	-> NOTE: It will still be a customized AMD64 machine, running a custom
	  version of CoreBoot.

Kernel: Start implementing MBCI support into the kernel.
