MasterPDF loosing all personnal certificates after restart

[flomine]

When restarted all certificates and signatures previously saved are lost.
It is related to #65.
As a workaround (already mentioned in #65) adding folder ~/.masterpdfeditor with flatseal solves the problem

cool. thanks for investigating.
I would appreciate if you could prepare a patch either symlinking the directory on startup of the app or exposing the folder in the manifest (I think it would also need the create permission).
