Improve repository searching for artifacts

Currently, if there are multiple repositories defined in poms and or settings, each time an artifact is retreived, it searches through the list, displaying warnings that couldn't be found for each repository. There are 2 enhancements that I can think of:

1. Don't print warning when it can't be found in the repository, unless it can't be found anywhere. This is just a neusance and clutters the screen. If it printed the url when it actually found it, I would be able to see where it came from and that's more than sufficient.
2. When looking for a jar, try looking where you just found the pom. I can't think of a good reason why it would be good to grab a jar from a repo different than where we found the pom. In this case, it just throws up a bunch more warnings when it should know where exactly to find the jar.
