Begin a basic command line interface.

Browse Source 
Add an external dependency to the docopt package and use it for a scaffold
command line interface for the cton-util command.

I am not too happy about taking external dependencies, and docopt pulls in 13
other packages. However, I really don't want to be writing command line parsers,
and as long as the external dependencies are confined to the tools crate, we
should be fine.

The core cretonne crate should stay free of external dependencies to avoid
trouble with embedding it.

Implement a basic 'cat' subcommand which currently behaves like unix 'cat'. It
will gain parser powers soon.
