Programs now built using IProgram interface

- The old App abstract class has been scrapped in favor of the IProgram interface in the Tomas.Interface library.
- A new terminal emulator was created when not on Windows.
- In both OS and terminal, a single dictionary has the commands and classes that implement IProgram.
- Start() now returns a boolean that behaves similar to C's main in returning an integer.
- A new while loop in both terminal and kernel handles the execution of programs.
