[Enhancement Request] Enhance the error notification for parsing wolfanim.script

[C-ColinTH]

For the wolfanim.script file in "models/[modelname]" folder, when parsing the content and encountering non-existent item names, the game will crash directly without any error notification, (For example, m30, which existed in the previous version, but has been removed in the new version). Also, the content in logfile with developer mode cannot clearly indicate the reason for the crash.

Suggest enhancing the parsing or error notification of wolfanim.script or other files like this, this will facilitate the debugging of modders.

Thank you!
