Implement an ELFImage struct
...
This struct allows us to keep track of what memory is used by the loaded executable. For some reason, freeing this memory when the task exits triggers a kernel page fault, so I'm not doing that right now.

Remove boot/font.psf from the initrd
...
This font file is not being used, since we are using an embedded font and that seems to work (should be loaded from the initrd in the future though)

Add LICENSE
...
I knew from the beginning this should be BSD-2 (my favorite license at the moment), but hadn't made a license file yet. Here it is!

Kernel: Do not stop interrupts by default in the interrupt handler
...
I always knew you can choose if interrupts are enabled for a specific ISR in the IDT entry, but at some moment there was a bug and I thought maybe that fixed it. Now reverting that doesn't break anything, so... let's do it :)

Add vprintf, (v)sprintf and (v)snprintf to libc + move the non v-printfs to stdio.cpp, since they can now call their v-variants and thus don't depend on internal_printf
