ls artist name inference

[adamrdrew]

We should be able to do:

$ mosh ls artist iamx

Without ever adding a shortcut for "iamx" because if we search for that artist we get only one artist back. We should allow inferring names by doing a search first and then using the result. More expensive, but we can decide its valid to infer if the input is purely numeric.

So

$ mosh ls artist 1234

We just do what we do now.

$ mosh ls artist iamx

"iamx" can't convert into a number, so we do an artist search. We get one result. We pull out the artist ID and then we search.

If the user provides a search that isn't unique enough just tell them:

$ mosh ls artist quartet
More than one artist matching "quartet" found. Please use an ID:
