The latest update introduced an issue where if it found an existing 
manifest, it would simply say it was loaded, but not do that. The 
attached patch fixes this, but also adds in color coding for error 
messages, allowing them to stand out.

Also attached is a depot validator. It is based on depot extractor, but 
all it does it read the contents of the depot's folder or the CSD/CSM 
pair, and validate the chunks. This doesn't use the manifests, allowing 
for anyone who downloaded every chunk from every manifest to be able to 
validate them all without ending up validating a file multiple times due 
to its presence in more than one manifest.
