Minor Changes
- Added a filter option to exclude non-exportable furniture.
- Removed wall height input option for walls with ceilings. To adjust the height, set the ceiling height instead.
- When creating a new room using the Create Room tool, roofs will be disabled by default.
Bug Fixes
- Setting wall height (for walls without ceilings) was not working.
- Setting the ceiling level was not working.
- Crash when a wall segment connected to a roof has 0 length.
