Continuing terminal I/O

- Made stdio.h work
- Moved printFiletable back into kernel.c
- TODO: Add stdio.h to all files that should use it (probably next commmit)
- Added some more global addresses. There's a memory layout, but i'm not using it
- Got cursor to be drawn
- Calc program now gets user input
