html template report contains encoded html tags

e.g. if you have a story

Then I say 'something other'

then the resulting html should be

<div class="step successful">Then I say '<span class="step parameter">something other</span>' </div>

but is

<div class="step successful">Then I say '&lt;span class=&quot;step parameter&quot;&gt;something other&lt;/span&gt;' </div>

What's happening is a double escaping. The StepOutput has a getParameterisedStep(String pattern) method that should be solely responsible for the escaping, rather than the Freemarker template macro (?html or ?xml).

We need to add a method getParametrisedSteps(Escape escape, String pattern) using the enum Escape

to determine which escaping needs to be done in the Java method implementation using the StringEscapeUtils.

JBEHAVE-813: html template report contains encoded html tags

correctly encode step pattern and parameters but not the html/xml tags that are inserted into the text in the report
(changes for the actual fix and added a few lines to the TemplateOutputBehavious as well as to the PrintStreamOutputBehaviour, this does the encoding correctly however)
To distinguish between XML and HTML I had to introduce an enum that is accessible from the freemarker template, which is kind of complicated.

(the commit also contains the changes for JBEHAVE-815, due to the necessary changes in the unit text result files it didn't make munch sense to put this in two commits)

sorry, left a debug statement in, please merge this commit as well
