romanization support in utf8 library

This patch addes basic romanization support to the utf-8 library. It
converts non-latin languages to ASCII.

The transliteration tables used where gathered from various places
on the net. I do not speak any of those languages so I can't say how
good they are. Any recommendations and fixes are welcome!

This can be enabled for ID cleaning by setting the deaccent option to 2.
It is also used in the XHTML renderer to generate section ids based
on the header titles. Leading digits and any remaining non-ASCII chars
are removed as well. This is the first step to make section ID always
XHTML compatible. Making sure they are unique is not implemented yet.
