[DOXIASITETOOLS-82] Decoration model body/footer type mismatch

Type of the footer has been changed to String according to its descriptions for several reasons:

* As layed out in DOXIASITETOOLS-50 the footer is supposed to be a text and not an XML fragement, site.xml has to be view agnostic
* footer snippet cannot easily be obtained because a complete XML document is returned
* a toString is not possible without complete tree traversal

For those who still want to have XML passed to the renderer, they can use a CDATA block.

[DOXIASITETOOLS-98] Decoration model's Modello doc point to a statically versioned schema file

Modello does not apply any property filtering, so adding a TODO and a comment in the POM and model file.
