Basic idea's are created for the storage solution

Browse Source 
- Added boot device info parsing to the kernel
- Added a pointer in the kernel to our pre-kernel BootInfo structure
- Created a layout for the FAT driver
- Created a layout for the virtual filesystem
- Separated IDE driver from the basic atapio driver.
	This will ensure we are not using one or the other
- The create_harddrive shell script will now actually build a harddrive image of
	the kernel
- The virtual filesystem initializes and creates a filesystem structure
	for every FAT16 partition in the master boot record
