SHRINKRES-5 Added method to use remote repositories without using XML fi...

Hello,

Looking for a simple Maven dependencies resolver/downloader, I eventualy came to the conclusion that SW resolver was the best in town but for one thing: it does not allow to add remote repositories through the API (it uses whatever repositories contained in the different maven conf files), which is a requirement of my current project (it is possible to interpret SHRINKRES-5 as the same issue, but I'm not sure). So I just forked it and added the function in a consistent way with the fluent API: [resolve()].withMavenRemoteRepo(name, url, layout). Test case is provided.

Please feel free to reuse it in case you deem it worthy of inclusion, and in any case thanks for your work on SW resolver.
