Add the ability to add user-defined properties using a new `openspace.addCustomProperty` function that takes an identifier and a type and creates a new property of that type. The new property is then available under `UserProperties.<identifier>`
* Some cleanup of the ImGUI code
* Reorder the panels
* Make StringPropertys work without losing value on context loss
* Add a new ImGui compoment that shows the status of the scene graph
* DPI scaling
1. Add the ability to query the operating system's DPI scaling values
2. Expose those values through a new Lua function
3. Add an asset that sets the CEF gui and the Dashboard font sizes and placements based on the DPI scaling
4. Add that new asset into the base_blank asset
* Add message when including the dpiscaling
* Backwards incompatible change to the astrocasting protocol
* Send password in the clear [never thought i write something like this]
* Update to new Protocol version, remove built-in ParallelServer
* Remove Wormhole server in favor of Typescript version
* Use linear camera path when within target bounding sphere
And do a workaround for speed computation when bounding spheres are large
Closes#1910 (by at least making it so that the camera moves in an observable speed)
* Make linear paths rotate based on time rather than distance (closes#1947)
Adapting Lua functions to new codegen functionality
Improve the documentation itself
Add some styling to generated documentation
Have parameter names for Lua-defined Lua function documentation

* Format property infos in orbital navigator more consistently
* Add helper function to trigger an idle behavior (issue #1833)
* Add timer to start idle behavior when camera is idle (issue #1730)
* Change spline curve parameter interval from [0,1] to [0,nSegments], for slightly increased precision
* Use linear paths whenever precision isn't enough/paths are too long (and traverse linear paths differently, to make them less depending on the distance)
* Remove OrbitalNavigator.LinearFlight and instead add "Zoom to" helper functions (closes#1837 )
* Add check to prevent triggering awkward short paths, for example when flying to the current target or to the same geo position twice
* Refactor speed code and handle speed when path is shorter than start+closeup distance
* Add easing to speed dampening
* Add topic for engine mode (to be used for UI later)
* Cleaner log when creating paths (some previous info messages are now debug messages)
