MAJOR REWRITE

- Kernel got pretty much deleted, will be rewriting in following days
- Bootloader got rewritten, stage1 works, stage2 will be written in following days
- Libc is still the same
- User will contains userspace stuff
- Rewrote makefiles again
- Got rid of backup (see previous commits for that)
- Image has 1 MBR partition for FAT32 which contains 'kern.bin' file
- Remade info files to be more "big project" style (all caps plain text)
- Added some dumb docs
