[Therion] Splays appearing when not selected

[Stacho Mudrak]

Hi,

survey selection was really ignored when splay shots 3D models were
exported. I hope, it is fixed in 5208297
<https://github.com/therion/therion/commit/52082975dddbe2601f84b82d334eb0c4cf944e05>.
Thanks again for finding out Rhys, that it was just a splay shots issue!

Tarquin, did you know, there is a "-walls off" option for scrap? It was
designed specifically for this purpose. To turn off wall generation from
unwanted scraps - low-quality surveys in your case. Or is there some
problem with using it? OK, you have to specify it for every scrap, maybe it
should be also supported for maps. Would it solve your problem?

The original idea was to generate walls from all available information
(centreline lrud, splays, and scraps) in the given survey. It is not yet
fully implemented but still remains a goal. Therefore selection by surveys
and not by maps. Selection of scraps in selected surveys for 3D export
works I assume.
