Hotfixes for 15 July - v0.18.19
Hi folks!  This is our traditional post-update 'hotfix' build after a regular update to catch stuff that wasn't caught during testing.
This time we have:
Oh.. and this build also adds four new wall visual styles! So I guess maybe it's not only a 'hotfix' build as I first said! ;D
Thanks for your patience and support, everyone! Next up on my list during the Creativity Spike is going to be a revamp to scenery placement!

This time we have:
- Tweaking navmesh generation just slightly.  We're seeing a lot fewer navigation mesh problems than in previous builds, but it hasn't gone entirely to zero yet, so this is just tweaking the procedure a little to see whether we can't minimise those issues.
 - Fixed the "click and drag mouse to rotate" building placement interface when angle snap is disabled;  it was feeling very weird and unresponsive in the last build.  Now fixed to be like in previous builds!
 - Fixed an string in one of the help messages which was using the wrong localisation key.
