This will first checkout a new branch, then apply the patch, and then create a commit for the patch with the message `Imported patch 'NAME'`, similar to what is done by mq. Afterwards a user can just delete the new branch when they're done with e.g. reviewing the webrev. Although, there is also an option to directly apply the webrev without creating a branch or commit.

Great work @JornVernee! Just a few tiny comments that you can fix before integrating :+1:

PR: https://git.openjdk.java.net/skara/pull/32

args/src/main/java/org/openjdk/skara/args/MultiCommandParser.java line 57:

Super tiny comment, and you can fix this before integrating, but I always prefer a positive check. In this case it would be `args.length > 0` to show that we can read the first argument.

Since you are using `HttpClient` now we should make a call here to `HttpProxy.setup()`

Maybe you want to rename this to `from` and instead take a `java.net.URL` as type for the argument?
