Kernel and SystemLib: See below.

What has been done:

- Rename most System.Core to SystemLib.
- Reworked it's API and the concept of ObjectRef to become the
  ApplicationRef object.
- Remove unused ODF and XIFF file format from tree, ODF will be part of
  the text editing program.
- Update Readme for SystemLib.
- Add Support folder on NewFS partitions.

What is next:

- NewFS filesystem support.
- Program loading.
- Preemptive scheduler on non-SMP systems using timers.
