Switched to grub

This really isn't what I wanted because grub is very big and bloaty but
my own bootloader was very poorly written and I really want to implement
a filesystem like ext2 which wouldn't work with my own bootloader.
Furthermore this commit fixes many small issues including the one
occurring due to the statically linked user binary (I just removed
the linking for now).
