What you were trying to do

Disable all manually-selected modules so that only the default selection for the gameplay template are used.

What actually happened

All modules are disabled, including the active module, which cannot be enabled or disabled from the UI.

How to reproduce

• 1. Ensure that you have multiple gameplay templates available, such as Terasology/GooeysQuest

Modelled on OPENVDB_USE_BLOSC, it would be nice to introduce OPENVDB_USE_ZLIB that could be used to make the zlib compression library an optional dependency.

This should be added to the core library, the CMake build system and the OpenVDB Read SOP and should default to ON.

The CMakeLists files of this project is kinda messy, mostly due to my limited understanding of the topic.

So they definitely need to be cleaned up at some point

The file dialogs should get the ability to store bookmarks and maybe even to show the default folders of the OS (like Downloads, Pictures, ...)

The custom bookmarks should just be stored as a Cvar (see core/Var.h, or in-game-console command cvarlist) that is separated with ;
