Standalone Garden editor app

[cfnptr]

There are currently no plans to create a standalone editor. Since in this case it is necessary to load the game code as a dynamic library and in case of a crash the editor will crash together with the library, unlike Unity. Also this approach limits the possibility to quickly view or change the code of the engine itself. The idea of the engine is that it should be added to the game as a third-party library and compiled together with the game, so the engine should be maximally convenient and understandable for integration.
