[Draft][OpenMW-CS] Don't use custom QSortFilterProxyModel for Info tables
Addresses issue #4357 (closed)
This fix "falls back" to basic sorting methods used by base class
IdTableProxyModel, and ditches
InfoTableProxyModel. I'm not however sure if there's useful code in
InfoTableProxyModel or if it should be removed completely. I don't see much use for it, especially if this will get merged: !512 (closed) .
Don't merge before properly reviewed!
