*	Fix next icon still being drawn when tool is inactive	Arne Dußin	2020-11-10	-0/+10
\| \| \| \| \| \| \|	The icon that would be placed next, but is not on the map was always drawn once the icon-tool was activated once. This is no longer the case. Also, the tool now saves the last icon that was selected and keeps the rotation of it between placements, which I deemed more intuitive.

	In order to be able to save and load the map, a major rework of the code seemed necessary, since Vector2 and Rectangle of raylib do not implement serialize, and it seems cleanest to use the serialize/deserialize traits of serde, to save for instance to RON. ToolShed was renamed to Editor, since it should better show, that it does quite a bit more than harbour tools. The map data is now centrally saved in the editor, instead of decentralised in the tool structs.
