Began the process of moving XnoeOS to using more OOP constructs. Added PageDirectory class. Added PageTable class. Added tuple data type. Added beginnings of the skeleton for Allocator and Process.

Properly print out the e820 entry types. Make kernel_directory and kernel_page_tables available to all. Add a memory unmap function. Update Makefile.

Fixed bug in GDT length calculation in bootloader. Kernel now loads its own GDT so it doesn't clobber itself while touching memory. ATAPIO now loads its own copy of the boot sector so it isn't reliant on 0x7000 being mapped. Removed debug printf statements from a lot of places.

The kernel is now actually useable with paging enabled.

Fixed paging fully now. Kernel is loaded with virtual memory enabled. Just need to write an allocator and make kernel use virtual memory addresses for its stuff. Restructured codebase to be less messy. Updated Makefile to put binary files under build/ rather than in root directory

Fixed structs for PDEs and PTEs, got Qemu now properly maps virtual addresses to physical addresses, still triple faults on but I'm getting closer to getting it fixed.

Completely changed how XnoeOS boots, organised the code somewhat, renamed kernel32 to kernel, now uses the 9 sectors after the boot sector to store a 32 bit stage2 loader. No longer spends unnecessary time in real mode. Updated atapio to properly account for the reserved sector count.
