Ensure require is usable within the REPL

Browse Source 
As 'require' operates relative to the current program's directory,
rather than the current directory, it meant we were trying to load files
from /rom/programs.

This is never a good idea, so we add the current directory to the
package path, allowing you to use require as one'd expect.
