File Manager Enhancements

[Hye-Dev]

The file manager needs:

1. The ability to create new files directly in the file manager
2. Syntax highlighting of common file types
3. Breadcrumbs should be clickable even when editing a file
4. The save button should save the file without forcing you to exit the file manager
5. File types that support syntax highlighting should also display special icons rather than just the generic file icon
6. The "open" button from the dropdown should not have different behavior than clicking the file
7. Add right click support to the file list (see this component)
8. If config["oci.cwd"] is set on an instance, the "home" button in the file manager should take you to that path, and the default path when entering the file manager should be such
9. If you drag and drop a file over the file manager, a dropzone should appear
10. File uploads should display progress as to their upload
