License tag for underlying tool in tool wrapper

[mvdbeek]

Our license tag describes the license for the wrapper. This doesn't have to reflect the license of the underlying tool. For non-academic users it is important to know if a tool is academic only. xref galaxyproject/iwc#47.

I believe we can probably extract this from bio.tools if tools are annotated there, but a standalone tag might be good as well.

Seems like this normalizes the use of restricted licenses. I guess this is a question for galaxy leadership though.

I'm not keen on implementing it or a friend of non-academic licenses ... but I also don't think we'd want to restrict authors on what they can wrap and at the same time we don't want to get our users (or ourselves) into trouble (hypothetically ?). If someone requests a tool on usegalaxy.* we don't go and check what license a wrapped package uses, so I'm seeing this as more of a tool to keep certain licenses out than an endorsement of restricted licenses.
