Make Maven download the necessary python libraries that pyoracc uses

[raquelalegre]

These plugin is working and easy_installing all the necessary python modules (although it gave some trouble with mako and jinja and I had to downgrade mako from v1.1 to v0.9.1), but they are not being properly imported by the jython code, can't figure out why.

            <plugin>
                <groupId>net.sf.mavenjython</groupId>
                <artifactId>jython-compile-maven-plugin</artifactId>
                <version>1.1</version>
                <executions>
                    <execution>
                        <phase>package</phase>
                        <goals>
                            <goal>jython</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <libraries>
                        <param>nose</param>
                        <param>ply</param>
                        <param>https://pypi.python.org/packages/source/M/Mako/Mako-0.9.1.tar.gz</param>
                    </libraries>
                </configuration>
            </plugin>

That maven plugin is downloading the libraries (mako, ply and nose) to target/classes/Lib.
To make the Jython code find these libraries, the PYTHONPATH needs to be extended to include target/classes/Lib. This can be done In the main Java entry point, like so:

systemState.path.append(new PyString("target/classes/Lib"));

Works now! :)
