Use the probably modified internal name of the template
in the template-details dialog before import.
Therefore the name of the qlineedit of the internal name of
all other details dialogs changed from "descr" to "description"
to match the name in the NewX509 dialog and to be found
by the "XcaDetails" class.
When exporting the template data, add the internal name and the comment
to the exported data.
The XCA template data is defined by us and can be modified.
This change is backwards and upwards compatible:
New versions of XCA can read an old Template export and vice-versa.
When XCA started in 2002, there were no C++ initializers.
Drop explicit initializers from the constructors.
- Fix indentations of section declarators.
- Replace NULL by nullptr when feasible.
- Sort private section: properties first, then methods.
The ImportMulti dialog does not show up if there is only
one item to display, but the item is displayed directly.
The displayed items have a new "Import" button to import
directly from the viewed item.
If XCA is called with certs, crls, keys etc. from the commandline
XCA only displays and optionally imports the item if a default
database is given. Afterwards XCA exits.
