Features

add "cameraCollision" attribute to bodies.
shader include statement now supports targets in datasets.
add on-demand re-compilation of post-processing shaders from their source files, in runtime.

position of context menu in dataset manager is off.
unknown dataset types crash Gaia Sky. Fixes #787.

wrong size initialization for raymarched objects.
prevent non-focusable objects to appear in search results and to be set as camera focus.
enable atmosphere/cloud procedural generation even when the surface is disabled due to cubemaps being used.
do not attempt setting a window icon in Wayland, it is not supported and results in a (harmless) crash.
position tracking does not work with objects in orbital elements group.
correctly populate window width and height in preferences dialog.

update configuration file version number. This implies that your old configuration file gets overriden with the new version during the first startup of the new Gaia Sky version.
