tags seem to be case sensitive

Tags seem to be case sensitive.

• I create a document with api tag
• I create another document with API tag

On both document, tag link is http://myserver/tags/api/.

But when I click on the link, only the first document appear, the one which have the api tag (lowercase).

So tags seem to be partially cas sensitive (the slug is lowercased, but the real tag is API or api). Is there a way to fix that?

Agreed. I think this is because metalsmith doesn't allow for two files which differ only by casing to be processed as separate files (correct me if I am wrong). Though the web spec for URLs technically allows it (aside from domains - google.com vs Google.com)

It'd be nice to make tags case insensitive, so an 'api' tag is the same as 'Api'. I'll work on a PR.
