Did a ton of stuff.

- Changed the file structure of the SuB Suite, so that
  all variable declarations, symbols, and constants
  are in a single file.

- Moved the C library functionss into a separate
  file, and made them use stack frames.

- Added support for using the emulator's assembler for
  realtime debugging, to enter it, get in to stepping
  mode by pressing Ctrl+s, press any other key, then
  press F1,
  The reason for having to press some other key before
  pressing F1 is because it only allows entering the
  assembler when the keyboard is not ready.

- Added the ".res" directive to the emulator's
  assembler, the ".res" directive tells the assembler
  to reserve however many bytes specified by the
  operand.

- Fixed some bugs in the emulator's assembler.
