Zeno Clash model converter

Zeno Clash uses a modified version of the Source engine and one of the changes is to the .vvd format (one of the files that makes up a model). This command-line utility will convert a Zeno Clash v5 .vvd file to a Half-Life 2 v4 .vvd file (not all files convert correctly).
