xades and pades zip file (docx, odt, etc..) sign not working

Created by: zsoltii

xades and pades can not sign odt, docx and any zip-ed file, the original code thinks from every zipped file, it is an asic file, which is not good idea, because for example odt, docx files are zipped files which contain lot of xml-s inside.

With this changes, you can sign odt, doxc, etc...
