Every so often there is some discusion about how to make MicroEMACS
recognise a certein key sequence eg. the directional keys on a VT100.
Given that people will want to bind a wide number of different keys
to varioius functions (different terminals and function keys) I
have rewritten the key binding method for MicroEMACS so that a function
can be bound to any particular key sequence (Except for those the use
^@ (NULL) in the sequence (this may be fixed later)).

When MicroEMACS is started up the first thing it does is read a startup
file that contains information regarding how particular functions are
bound to a particular series of key-strokes. It uses something like the
following sequence :

[ Command		Function		Key Strokes ]

  bind-to-key		forward-character	\e[C

The above example will bind the forward-character function to the
keys strokes that are emiited when pressing the right arrow on a VT100
terminal. There is also a way of defining special charater values.

Obviously reading in the binding file every time is not the best way
of starting up MicroEMACS so it is possible to create a preloaded 
version. This is achieved by causing A core dump from the loadup file
by the command 'core' and then recreating a runable executable from this
preloaded core file (BSD4.3 only at the moment as far as I know). This
means that only a small number of keys need to be defined in the loadup
file.

I have retained all of the normal functions provided it MicroEMACS to
do with key bindings etc but the syntax is changed slightly. The changes
seem to work O-K but I will not gaurantee them to be bug free.

If enough people are interested I will tidy it up and post it out (this
will probably take a couple of weeks).
