Serene bed recipe has had a change of sheets (previously created a Solaris bed.)

Added sloped serene, geometric, doom and executive hull panel tiles.

Touch up on graphic recolors for some opulent tiles.

Solaris furniture set now includes table and chairs.

All tiles/platforms are now paintable. For executive tiles, the 'highlight' parts are recolored so some like the panels will show no change.

Recipes added for the vanilla themed furniture sets for Serene, Geometric, Wave, Opulent, Doom, and Executive, making these objects available from the Industrial Workbench.
