Fix references to examples in api documentation

The documentation displayed references to examples in the main docs but not in
the corresponding api reference docs.  The build had these warnings..

: WARNING: Include file u'/Users/khaido/workspace/jenkins-job-builder/doc/source/api/
../../tests/properties/fixtures/batch-task.yaml' not found or reading it failed

As pointed out by Darragh[1] the problem was that literalinclude needs a leading '/' to
correctly reference both docs.

make job creation consistent

Defining a project (in yaml) without setting any other parameters should
generate a basic jenkins job (in xml).  While this works for freestyle jobs,
jjb will throw an error for maven and flow projects.  The behavior should be
consistent across all types of projects.  This patch just makes it so
that the behavior is consistent.

tests: Allow to test project parameters

So far it wasn't possible to test the prameters of the
project itself. While If7b749dae7631e8714a9416dfbd82d2443c0302c
already made the job creation consistent this goes one step further
and creates the root_xml using the project's root_xml method.

project_maven: Don't require artifact-id and group-id

Jenkins will determine the values from the pom automatically so there's
no need to require them.

Add tests for YamlParser and patch 2.6 minidom

Test full build job XML produced by the YamlParser object which exposed
differences in how the XML was being written on python 2.6 versus newer
versions of python.

Differences were whitespace only, but made testing and validating the
xml outputted across multiple versions of python difficult.

Code now patches the python 2.6 writexml method on the Element class in
the xml.dom.minidom module, with a version of the method taken from
python 2.7.5.

Removed the now obsolete regex that was reformatting the output on
python 2.6.
