[Therion] Build a map with all centerline and partial walls

[Bill Gee]

Actually, I would like full detail where it exists and centerline only 
where it does not.  Martin's hints give me an idea how to get this.  It 
will take a day or two for me to set it up and test.

I also want maps where only the drawn stuff is shown.  I think what I 
need to do is leave those parts of *.th2 and thconfig alone, and add new 
stuff as noted by Martin.

One additional question regarding the "select" statement location ...  I 
think I need to put it in thconfig just before the layout and export 
lines that creates the file, like this:

======================  thconfig  ============
select MainPlan

layout basics
...
endlayout

(more layout sections)

export map  -proj plan -layout ChosenLayout -o Outputfile

(several more "export map" commands to get Loch, Aven, KML etc files)

select FullMap

layout FullMapLayout
...
endlayout

export map -proj plan -layout FullMapLayout -o AnotherOutputFile
======================

Is this about right?

Another way I might do it is to create entirely new thconfig and *.th2 
files just for this map, then use a "system" call in the main thconfig 
to launch another instance of therion with the alternate thconfig as a 
command line option.
