This is the beginning of setting up a flexible way to open items beyond the text buffer -- think notebooks, images, GeoJSON, etc. The primary requirement to allow opening an arbitrary file is `try_open` on the `project::Item` trait. Now we can make new `Item`s for other types with their own ways to render. Under the hood, `register_project_item` uses this new opening scheme. It supports a dynamic array of opener functions, that will handle specific item types. By default, a `Buffer` should be able to be able to open any file that another opener did not. A key detail here is that the order of registration matters. The last item has primacy. Here's an example: ```rust workspace::register_project_item::<Editor>(cx); workspace::register_project_item::<Notebook>(cx); workspace::register_project_item::<ImageViewer>(cx); ``` When a project item (file) is attempted to be opened, it's first tried with the `ImageViewer`, followed by the `Notebook`, then the `Editor`. The tests are set up in a way that should make it _hopefully_ easy to learn how to write a new opener. First to go after should probably be image files.
