Fix issue with some files having non-unique modifier names

Originally the files are coming from ancient early-2.4x epoch, but in
theory such setups might have been re-saved multiple times already with
more recent blender versions.

So the verisoning code is applied on all the files, including very
recent ones.

Bumped subversion, because this check si not really cheap.
