Feature/#51 make geometryitems clickable

[DorianRec]

This recognizes the GeometryItem nearest to the mouse-clicked position.
GeometryItem will be printed out via log.info() and "highlighted".

Changes:

• Added a class Treasure.
• Added class Selectable, which SearchPath, Hint and Treasure extend.
• Gave all Selectables a method getGeometry, since all contain one selectable Geometry - object.
• GameEngine now creates new SearchPath-Objects containing all LineSegments, of the searchers searchPath, instead of lacking the first LineSegment. This makes the SearchPath Class much easier to use, since we do not need to give it the first point of the searchpath in order to get the search path.
• Gave GameManager the method List<Selectable> pickGeometry(Coordinate mouse, double distance), which returns a list of Selectables, the user may have selected.
• Gave GameManager the method void refreshHighlighter(Coordinate coordinate, double scale), which selects a new Selecable. Thus, the method is called, when the user clicks the coordinate-system.
• Gave Turn the method void unselect(), which unselects the SearchPath, Hint and Treasure, the Turn contains.
• Gave Turn the method List<GeometryItem<?>> getSelectedGeometryItems(Point movementStart).
• Removed the variable visible from the class GeometryStyle, since it was never used and is useless.
• Gave JTSUtils the method static Polygon toPolygon(Envelope envelope).
• Gave the Renderer the method static Stream<GeometryItem<?>> getHighlighter(List<Turn> turns, int viewIndex).
• Changed the method void onCanvasClicked(MouseEvent mouseEvent) in CanvasController, such that selecting of an Selectable.

Issues:

• Non-Scaling GeometryItems, like AngleHint are not highlighted correctly,
  but this is out of the scope of this issue!

Bugs:

• Does not works after scolling
• Distance between mouse and clicked GeometryItem should not be dependend on the inGame distance, but on the distance on the canvas
• Dragging the canvas also executes the mouseClicked-Method
• Selecting a LineString highlights its first point
• There are some invisible LineStrings on the canvas getting selected by my algorithm (?) EDIT: This is the fixed-scaled AngleHints
• Repaint the canvas after new GeometryItem selected (and not dragged the canvas)
• Add selected GeometryItem to an EventBus
• Change Guava EventBus to the newer one
• Iterate through Items, when clicked on same spot.
• Pick GeometryItems correctly regarding distance.
• Exclude older treasure locations from being selectable.
• Exclude 0-element LineStrings from being selectable. (This will be fixed with Invariant: SearchPath 0 or ≥2 Points #186)

Fixes #51
Fixes #181

@DorianRec wenn noch einmal jemand System.out.println benutzt, **** ich jemanden XD

good first state, some changes for selection need. Have you implemented a neighborhood distance in which to search for clicked elements? For example, if just one element is present, clicking everywhere selects this item.

Fixed with last commit

In the end highlighting the stuff with additional object seems a bad idea to be especially because be need to create specially designed Geometries for this.

Maybe we can look into it and see if we come up with a simpilier solution 🤔

Also this has conflicts

If i highlight somthing and then go back it won't remove the highlight:

Also what about the maybe we remove the highlight things ountil we have some Ui and stuff to it

[1-alex98]

Well what I said above
