Create UI for viewing dependencies

[rwinch]

It would be very helpful to provide a UI (similar to m2e) for viewing the dependencies and dependency tree within Eclipse. This is a key source of frustration for me when working on large projects and trying to sort out classpath issues.

NOTE: I realize that I can use the CLI, but with large number of dependencies this is difficult to use. For example, trying to follow | up 20 dependencies to its parent dependency is difficult. I can use dependencyInsight, but I don't want to run this command a dozen times to sort out classpath issues.
