Refactor a major part of the project
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.
