tdf#155665 Adding option to remember signatures for each save

Added the option in digital signatures dialog to remember used
signature.

Implemented ResignDocument function in objserv.cxx to resign after
every save in case the option to remember signature is on.
Added a new dialog box that checks whether there is a need to
remember the signature.
