[FIXED JENKINS-5044] catch FileNotFoundException if mojos are executed from a classes directory instead from a jar

Pull individual Dependencys out of DependencyGroups we see in
BuildTrigger.execute and make sure to actually kick those builds off
as well, so that we can have two different dependencies (say, for
different parameters) from one upstream project to a single downstream
project.

[FIXED JENKINS-9691] Boldify names of executed mojos for Freestyle and Maven2/3 jobs using Maven3 in console output.

Maven2/3 jobs using Maven3 in console output.
With Maven3 the output format for mojos has changed:
- Add a new Maven3MojoNote and use it in MavenConsoleAnnotator.
- This is sufficient for Freestyle jobs running Maven2 or 3 and Maven2/3
  jobs running Maven 2.
- Maven2/3 jobs running Maven 3 are using ExecutionEventLogger for
  printing start of mojo execution to console.
