lok: add signDocument to "Office" iface - to sign not opened docs.

LOKit function "signDocument" can sign document without the need
to open them. This is useful to sign PDF documents after they are
created from a currently opened (ODF, DOCX) document.

This adds DocumentDigner to sfx2, which could also be used in
desktop LibreOffice without opening them and in further tests.
