Consistently use ~T() override; in class declarations (so no virtual in front, and avoid warnings due to the missing override in back).

|
|
* old code for PluginFactory was a fork of an old version of
|
|
* exactly that).
|
|
*
|
|
* The current createInstance() method passes more arguments
|
|
* to the job and viewstep constructors than we want; chasing
|
|
* that change means modifying each Calamares module. This class
|
|
* implements a version of createInstance() with fewer arguments
|
|
* and overloads registerPlugin() to use that.
