- this now searches VFS/PAK files in addition to the filesystem
- if FLAG is 0 then ONLY dirs are searched.
- PAK's are searched before DIRs to mimic engine behaviour
- index is ignored when searching PAK files.
- when searching VFS, files are searched case insensitive.
-
- WARNING: if you use index from vfsGetFileCount, it works only with a vfsGetFileCount for the search directories only (not the pak files)
- FIXME TTimo our VFS names are case insensitive.
- this function is not able to build the full path from case-insensitive name
