Sync AUTHORS and DONORS file with master branch

The new authors were not necessarily involved in the maintenance
of the 2.1 branch, but they matter to the project nevertheless :)

The donors are added for the sake of documentation, but not listed
in the About dialog of the editor for now (the feature parsing that
file to generate this content was not backported to the 2.1 branch).
