Warn about unsaved scenes before commit

[bartlomiej-dawidow]

To reproduce:

1. Make some changes to a Unity scene, e.g. rename a GameObject.
2. Edit a script in Rider.
3. Commit changes to git.

If you do not save the changes done in Unity, they will not be included in the commit. I routinely find myself forgetting to do this.

A suggested solution would be to add a prominent warning message somewhere in the Commit Changes dialog if there are any unsaved changes in Unity.

I wonder if there is any api to check unsaved scenes in UnityEditor.

Yes, you can call Scene.isDirty to see if it's modified in memory, and use something like EditorSceneManger.GetSceneAt to iterate over all open scenes. I need something similar for the YAML stuff (don't want to rename something referenced in an unsaved scene), so I can look into this as part of that.

for (var i = 0; i < SceneManager.sceneCount; ++i)
    if (SceneManager.GetSceneAt(i).isDirty) ...

We have already do same check for Find Usages in scenes, so it is possible. But the connection should be established for this feature
