Add the Ficl (Forth Inspired Command Language) interpreter. If all goes well,

this will allow us to manage bloat in the loader by using a bytecoded HLL
rather than lots of C code.  It also offers an opportunity for vendors
or others with special applications to significantly customise the boot
process without having to commit to a divergent code branch.

This early commit is to allow others to experiment with the most effective
mechanisms for integrating FICL with the loader as it currently stands.

Ficl is distributed with the following license conditions:

"Ficl is freeware.  Use it in any way that you like, with the understanding
 that the code is not supported."
