Restructured cabalized project

Moved hack assembly parser into its own library, as this is a more
modular setup and opens the possibility of adding additional front
ends (Eg. a web front end).

Currently there is one executable 'Asmblr' which is the command line
front end. See README.md for more details of its operation.
