convert_to_ascii in DADA::App::Guts strips out characters like, Ü, ß, etc

[justingit]

"convert_to_ascii" is sort of a bad name for this subroutine, as there's no real need to convert anything to ascii before, so the methods used to do so, are outdated.

What convert_to_ascii really does is take HTML text and changes it to unformatted (with HTML tags) plain text. This text can really be with characters above 7bits, without any problems,
