Dev Update - v0.19.119
Hi folks!  This is a small general update with some performance improvements and some placement tool improvements.  These include:
Big thanks to everyone who submitted saves to demonstrate these issues! They made it a lot easier to track down the problems!

-  Improved the wall placement tool to make it easier to join walls together.
 -  Walls now do a much better job at reliably building obstructions into the navigation mesh.  (previously they would sometimes be truncated or have small gaps in tight corners)
 -  Vast speedups to navmesh generation, especially in regions containing a lot of walls.
 -  Fixes an issue with pasting multi-line text into a single-line text edit box.
 -  Fixed a lot of activities which weren't testing the 'island' system to validate themselves, which could result in subscribers getting stuck in a pathfinding loop, which would then hog pathfinding threads and cause other subscribers to spend a lot of time standing around and waiting for legitimate paths to generate.
