[esp-r] further draft of a common constructions file

[Jon Hand]

After recent comments on the initial draft I have regularized the syntax so that
there is a space after the *key word and comma separated entries on the lines.
I added *docclass tag for the line of documentation for construction classes
and *docitem for the line of documentation for each construction.  This is a
bit more readable.  The edited example file is shown below.

The initial phase of freeing the code from the FIXED format for the construction
attributes (name, optical properties, link to reversed construction) is essentially
complete and the code now works by scanning the construction attributes into
separate variables for each attribute and then the code uses these arrays
rather than working with the DESC array (which required decoding at each
instance as well as local variables).  

Having moved away from the fixed formating we are free now to look at the
code blocks which have only been interested in the initial 12 characters (single word)
construction attributes and generalize them to work with longer phrases.  For
now, the names of optical properties will remain at 12 characters and when
that file format becomes the focus of attention we can loosen up that attribute
constraint.

Again, I might have forgotten something so your comments are appreciated....
