Bootloader: Clear screen, better memcpy
...
Clear screen before jumping to kernel. Memcpy now uses ebx as offset
register, so only one register has to updated every loop

Bootloader: Implement basic ext2 filesystem
...
This can search for files in an ext2 filesystem. Only 12 blocks
are currently supported.
Now only ELF loading is missing for loading the actual kernel!

Bootloader move bootloader code from arch directory
...
The os itself only supports x86 so this won't matter. x86_64 and i386
use the same bootloader assembly.

Bootloader: Continue work on bootloader
...
Bootloader can now get the memory map and read cmdline from user.
Now 'just' video mode query, ext2 and ELF parsing are needed :D
