9c5667c454 Created a proper driver for the serial bus
* The driver can write to any of the pre-defined serial COM ports
* The driver can read from any of the pre-defined serial COM ports (Untested)

5781f730d9 Implemented the basis for syscalls
A software interrupt with vector 0x50 will cause a syscall to start executing.
The EAX register will hold the syscall_num.
Other registers and the stack can be used to hold further arguments.

e6901f0526 We can now open and read files on the harddisk through a messy virtual filesystem
The uri has to contain 8.3 filenames for now as I have not yet figured out
how to convert from that to regular filenaming for the name comparison.

reading files is still limited to 1 sector

a77621faf5 Shellscript improvement plus FAT driver implementations
- Improved the run bash script to exit when an error occurs in one of the sub tasks
- Wrote basic FAT16 functions that should give enough information to properly implement the rest of the driver
- FAT structure namings are now in accordence with the microsoft spec of March 2005

50bf952a49 Basic idea's are created for the storage solution
- 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

81f7351fe6 Created a few shell scripts to update and create an build of the Kernel/Operating System.
A python script can be run to run the scripts in the correct order and immediatly try the build.
