Changes the jdk used by travis to OpenJDK (#176)
Changes the jdk used by travis to OpenJDK (#176)

* adds the possibility to use maven from a local installation

this will basibally tell shrinkwrap resolver not to use a specific
maven installation, preventing it to download it from the internet
and, instead, using it from the local (either from maven.home or
M2_HOME env variables).

This behavior is specified here:
https://maven.apache.org/shared/maven-invoker/apidocs/org/apache/maven/shared/invoker/Invoker.html#setMavenHome-java.io.File-

This feature is useful when running arquillian tests from within
an environment with no internet access.

* sets M2_HOME, when absent, using the dir when maven is located at travis-ci machine

* renames tests to follow project's convention

* changes the jdk to openjdk

licensing issues with oraclejdk were braking the build
