* Remove unused feature that allowed us to "pick" nodes using touch (it didn't really work and had some nasty hardcoded and costly implementation). Fixes Touch interaction picking refactor #1041
* General refactoring of code and removing redundant code
* Make touch markers prettier (change default color and smoothen edges)
* Add module property to control which renderable types are "directly touchable"
* Add SGN property to control which individual nodes are "directly touchable" ("SupportsDirectInteraction")
* Fix stuttering when zooming in closer than the orbitalnavigator allows
The printout is verified to be the same as before, except for 1) some escape characters which are no longer necessary and 2) strings that contained arrays have now become arrays in the json
* Cleanup Property code
* Remove NOLINT statements
* Return Property class types as string_view
* Remove getStringValue function
* Simplify string value retrieval
* Ensure that image paths in the ImageSequenceTileProvider are sorted (closes#2205)
* Some cleanup of OpenSpaceEngine
* Cleanup documentation
* Some more cleanup of engine classes
* Some more cleanup
* Update SGCT repository
* Use new Jenkins node identifiers as the old method broke with update
* Define WIN32_LEAN_AND_MEAN and VC_EXTRALEAN globally
* Use forked version of TUIO, some more work on precompiled headers
* Improvements for the Kameleon module
* Add the loading of a hash for wwt image files and automatically force a redownload of the files if the hash has changed
* Move the wwtdataimages location into the sync folder
* Some general code cleanup
Fix interaction problems when hovering/clicking with the mouse in a non-GUI window, when having a setup with more than one window (e.g. the single_gui.json setup)
Previously, clicking with the mouse in the rendering window without the GUI also triggered mouse clicks in all the other windows, including the GUI windows. This was disturbing for interaction in the single_gui setup
Now, the GUI modules check to see if the clicked window is actually an interaction window
