CLanguageList::Init() assumes pre-R16 resource directory structure

[NiklasRosenstein]

This causes CLanguageList g_LanguageList; in globals.cpp to be initialized with zero languages, effectively causing a crash in CStringTableElement::SetItemText() (if not earlier) when a description is being saved with ResEdit.

This is the respective code in LanguageList.cpp

dc2f7cd uses preprocessor definitions to check the API version, but we must base the decision on the runtime version of Cinema 4D.
