New classes:
- database_model: Manage the database tables (keys, req, cert, crl, templ)
extracted from widgets/MW_database.cpp
- arguments: parse commandline, dynamically create help text
No need to translate "X Certificate and Key management",
"Form", "Dialog" or "TimeInput"
"Select Token" and "New Key" window titles were never shown.
Remove them.
Better support multiple selections
- Export all selected items into one PEM file
- Batch Revoke/unrevoke/renew of many selected certificates
of the same issuer
- allow exporting templates as PEM
Add Feat. Reg. #83 Option to revoke old certificate when renewing
Always put all signed certificate to the newest CA.
If a CA certificate is renewed, all certificates issued by
the old CA are now shown as signed by the new one.
