Changelog: Introducing enemies

The highlight of this update is that there are now enemies!

This is the first update in a long time because of a private happy event, and also because this change took longer to implement than what was initially planned.

Additionally, it contains many engine improvements that will be needed for the future updates.

Finally, it is not in the game yet, but the foundations and main parts of the story and the world building are ready too.

Major changes

• Added a new enemy: the Barnian drones. They randomly spawn and move around the map, school together and attack if you come too close.

• Added scaffoldings, which can be used both for building and as ladders

• Dropped items now inflicts damage to entities, depending on their mass and speed

• The tech tree has been replaced with a simple list of recipes.

• The recipes list shows a indicator for the ones that requires power to be used.

• Researching something does not automatically add the blueprint to the inventory anymore. Instead, blueprint for a recipe can be printed from the list.

• Added buttons to open the recipes and inventory with the mouse

• Changed the engine used for sound processing. As a result, the sound and music channels are now separated in the OS settings and screen recordings or streaming
