Fixed cd. Now just typing 'cd' will bring the user to his home
directory.
Implemented redirection.
Tiny shell can now be exited without killing its parent when
recursively called from inside each other. The 'exit' command
must be used to stop the tiny shell

Bugs: realloc at the arguments is still giving some problem.
      There is memory leak there which must be fixed.
