Now the bootloader is divided in stage1 and stage 2, the kernel isn't loaded so it's useless (for now).
The Stage 1 of the bootloader prints some strings and loads the second stage into memory. The second stage prints a hello world message.
After this commit I'll divide the main branch into stable and coding (stable is working code, like all the commits I did until this day, coding will be the branch where I push all the code I write, so there may be a lot of errors or the code doesn't compile. I you want to use or just try XanvicOS use the stable branch)
