[Stacho Mudrak]

Hello everybody,

I have just uploaded version 5.3.9, which includes mostly bugfixes.
Here is a list of them:

- added missing area flowstone and moonmilk into legend
- fixed xvi export of extended elevation
- fixed symbol-hide/show point remark bug
- fixed wall:debris bug in AUT symbol set (thanks to Georg Pacher)
- fixed layout color map-bg transparent bug
- LRUD area dimensions is drawn for all shots before these shots are drawn
  (centerline is compact when map is exported from centerline only)
- vthreshold should work now for loch LRUD modelling

+ added option -enable/disable splay-shots to 3d model export
