Detect deleted AOT objects

[min2sia]

In case AOT object was exported to source control but later was deleted from AOT.
When doing regular export, such situation won't be detected.
Need to create function which will scan repository files and check if corresponding AOT object exists. If not - delete.

How about just deleting all files in the exported path (on the filesystem, not through git) and re-export everything and let git handle the differences? From an AX standpoint, deleting a class and creating a new with the same name is making a different class (different object id), but from change tracking standpoint it doesn't matter.
