More trimesh stuff

Cleanup: spelling

Cleanup: Make function private

The "UI_panel_set_expand_from_list_data" doesn't need to be in the

This commit just sets the expansion automatically and adjusts some
naming to account for the moved function.

Fix use after free deleting object with modifier panels visible

It's necessary to check if the panels are active before accessing their
data. Thanks to @ankitm for reporting this.

Cleanup: Use LISTBASE_FOREACH macro in outliner code
