[Rest2web-develop] Adding some debugging info

[Gael V. <gae...@no...>]

Just upgraded to rest2web 0.5.0 and my embedded code is crashing r2w. I
added a few lines to "embedded_code.py" to print some more debugging
info. I am sending the file only as I am really lame with diff. Could
the changes go upstream ?
