Added recursive traversion of all folders in each level

* enables representing the result folder structure in the source
** e.g. the "page.xsl" transformation is located in "source/pages" and the result is therefore written to "target/pages"
** this enables simplification of target metadata as it is now automatically relative to the level
* modified page template accordingly
