MDEP-779 show class names used in undeclared dependencies

[josephw]

This adds the class names tracked in this PR to the UI, when -Dverbose is set:

[WARNING] Used undeclared dependencies found:
[WARNING]    xml-apis:xml-apis:jar:1.0.b2:compile
[WARNING]       class org.apache.xmlcommons.Version
[WARNING] Unused declared dependencies found:
[WARNING]    dom4j:dom4j:jar:1.6.1:compile

It also includes the small changes necessary for any upgrade of maven-dependency-analyzer to 1.12.

To allow this to be reviewed ahead of a release of maven-dependency-analyzer, the version is set to 1.12.0-SNAPSHOT; if approved, it'll presumably be 1.12.0. As mentioned, it ties the new output to -Dverbose; I think this is simpler than adding a new specific property, and less disruptive than enabling it by default.

Following this checklist to help us incorporate your
contribution quickly and easily:

• Make sure there is a JIRA issue filed
  for the change (usually before you start working on it). Trivial changes like typos do not
  require a JIRA issue. Your pull request should address just this issue, without
  pulling in other changes.
• Each commit in the pull request should have a meaningful subject line and body.
• Format the pull request title like [MDEP-XXX] - Fixes bug in ApproximateQuantiles,
  where you replace MDEP-XXX with the appropriate JIRA issue. Best practice
  is to use the JIRA issue title in the pull request title and in the first line of the
  commit message.
• Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
• Run mvn clean verify to make sure basic checks pass. A more thorough check will
  be performed on your pull request automatically.
• You have run the integration tests successfully (mvn -Prun-its clean verify).

If your pull request is about ~20 lines of code you don't need to sign an
Individual Contributor License Agreement if you are unsure
please ask on the developers list.

To make clear that you license your contribution under
the Apache License Version 2.0, January 2004
you have to acknowledge this by using the following check-box.

• I hereby declare this contribution to be licenced under the Apache License Version 2.0, January 2004

• In any other case, please file an Apache Individual Contributor License Agreement.

We need some tests to confirm regressions in next releases.
Please add IT test with output verification.

There is test src/it/projects/analyze you can try to extend test verification

We can use groovy script here ... and we needn't external dependencies.
look for build.log reading in another groovy scripts

[slawekjaranowski]
