More Robust Resources Manager

Being able to add any, and I mean ANY kind of resources into your project, as its the only way to access non-resource type files in-editor without figuring the mess of loading files. This can be useful for some extensions like ones that use text files different than .txt or .json .

One of the things I would do with this is actually load in .obj files as resources since I also did some 3D stuff using PANDAKO’s extension. And no, its not only just for that, we just cant use gdevelop to load any outside files without some js stuff and even then we cannot access or get the file path because of stuff related to this engine.
