Service signer, Add DTD catalog / resolver

[GoogleCodeExporter]

ePub (and other file formats) may contain XML files with a DOCTYPE.
A resolver is to be added, probably somewhere in
AbstractXmlSignatureService.getXmlSignatureDigestValue

It might be wise to use local copies of well-known DTD's

Another use case: signing ODF-files containing MathML formulas.

OOo adds a DOCTYPE at the top of the (embedded) content.xml containing the 
MathML 
formula, causing a FileNotFoundException when the service tries to load math.dtd

Could you send me a hello world ODF with a MathML formula embedded?

DocumentBuilder.setEntityResolver should to the trick.
