updated maven and adapted aether, also had to exclude old version of asm causing headaches
changed package for aether classes to org.eclipse and fixed where changed, current it compiles but tests fail NoClassDefFound org/sonatype/aether/RepositorySystemSession, not sure where that comes from
javadoc update removing sonatype aether reference
using new snapshot of plugin harness that should fix the problem once released
o use maven 3.1.0
o force the use of sisu's ASM (to avoid a conflict in testing)
o use new plugin testing tools which have been updated for maven 3.1.0 (to avoid aether conflicts)
Merge pull request #222 from jvanzyl/maven31

o use maven 3.1.0
updated to maven 3.1.1
prerequisite changed to maven 3.1.1
downgraded to pluging testing harness 2.1 since it works again with maven 3.1.1 in master
Merge branch 'master' into maven31

Conflicts:
	pom.xml
changed creation of repo session
updated plexus utils to get access to org/codehaus/plexus/util/xml/pull/EntityReplacementMap
still need 2.2-snapshot of plugin testing
fix for har file lookup specific to architecture
