XEH - Fix missing XEH on GM objects

[commy2]

When merged this pull request will:

• fixes XEH on some GM objects
• close XEH - GM has two classes that don't support XEH #1365
• I didn't test this. Please test this. You don't have to check if XEH works, just start with GM on any mission and check if any error messages pop up and if the mentioned error messages correctly disappear.

Works with the compat mod, which I think has the same configs

Built and tested on full GM version, no XEH errors
