links and vendor

[djdv]

I think gx-go link should warn about the existence of a dependency that is both linked and also exists inside of ./vendor/

I got confused when I tried linking a dependency after forgetting I vendored everything previously with gx install --local.
gx-go link *somehash* will succeed in writing the package to global and linking but this has no effect since vendor exists with the dep inside of it. I'd like to see something like

>gx-go link QmWi28zbQG6B1xfaaWx5cYoLn3kBFU6pQ6GWQNRV5P6dNe
writing package to: C:\Users\Dominic\Projects\Go\src\gx\ipfs\QmWi28zbQG6B1xfaaWx5cYoLn3kBFU6pQ6GWQNRV5P6dNe
linked QmWi28zbQG6B1xfaaWx5cYoLn3kBFU6pQ6GWQNRV5P6dNe C:\Users\Dominic\Projects\Go\src\go4.org\lock
Warning: link succeeded but "go4.org/lock" is vendored

Both for links being created and links being listed with gx-go link

>gx-go link

Warning: "go4.org/lock" is linked but is also vendored
