The pattern to construct `Application` was to use the `try_create` method from the `C_OBJECT` macro. While being safe from an OOM perspective, this method doesn't propagate errors from the constructor. This patch make `Application` use the `C_OBJECT_ABSTRACT` and manually define a `create` method that can bubble up errors from the construction stage. This commit also removes the ability to use `argc` and `argv` to create an `Application`, only `Main`'s `Arguments` can be used. From a user point of view, the patch renames `try_create` => `create`, hence the huge number of modified files.
