alpha v1.2.0

a very rudimentary release, with many bugs (especially with user programs)
but, i have separated shell from kernel, and abstracted the FS*

i am in a weird middle stage in between migrating from cd to hdd,
thus we require both an iso and img (as the iso contains kernel.bin and grub)

to run, simply do
qemu-system-x86_64 -debugcon stdio -cdrom dekos.iso -m 128 -boot d -soundhw pcspk -hdb fat32.img
(hdd must be slave ata (or internal dev 4), as there is no way to change it as of right now)
