New content and balancing
* Added recipe to digest eggs in anaerobic digester.
* Increased orbital cargo limits.
* Optimized train driving to reduce slowdowns and waiting by taking other trains’ speed and inertia into account and allowing double-reservations, assuming that trains cannot stop instantly.
* Old odd-sized level crossings were marked obsolete and cannot be placed via copy-paste or blueprints.
* Improved program startup speed by loading data while the initial loading animation is shown.

UI improvements and QoL
* Train cars can now be flipped horizontally in the trains designer.
* The last selected item in the build menu is now persisted between saves.
* Train and line errors now shop-up in the lines manager.
* Added quick remove for sorter.
* Vehicle mass-replace tool now allows to filter vehicles assigned to tree harvesters.
* Unity key can be now used to trigger quick-remove and to toggle boost on a currently selected machine.
* Improved construction jobs aggregation when trucks carry materials from deconstruction directly to construction.
* Added ability to reassign a deleted station in a schedule.
* Added list of trains currently heading to a station to the station inspectors.
* Added a list of lines that have this station in their schedule to the station inspector.
* All terrain tools now have the flat designation as default.
* Copying of connectors via C key is now allowed and supported.

Fixes
* Level crossings now preserve no-stopping zone state through copy-paste and blueprints.
* Trucks should no longer exit in the middle of a level crossing, potentially getting struck in between train tracks.
* Fixed memory leak caused by housing previews. This also reduces the memory footprint of house models for settlements with more than 8 houses.
* Fixed that camera heights was not properly updated when panning to locations, such as when clicking on notifications.
* Fixed arc furnace disappearing from silicon toolbar.
* Fixed notifications tabs collapsing to too small height when they are all showing.
* Fixed max unity display.
* Fixed research complete notification showing +1 tier for incremental research.
* Fixed train and generator fuel stats that were incorrectly swapping on each load.
* Fixed that train was unable to pass though a loop at the end of bi-directional track if it was marked as critical section.
* Fixed rendering of symbol-based languages where the very top was sometimes cut-off.
* Fixed vehicle replacement that was not properly re-applying vehicle config if the vehicle was scrapped in a different depot than where the replacement vehicle was constructed.
* Fixed black screen when the game is loading before the main menu is shown.
* Fixed that non-storable products did not show in product statistics.
* Fixed rare issue with particle erosion during the map generation.
* Fixed issues with vehicle navigation overlay that was trying to compute values outside of the map.
* Fixed issues related to clearing connectors.
