[RFC] Don't always open a new dolphin tab when compressing a file
When running ark from one of the fileitemactions it always open a new dolphin tab/window. A setting exists to control this behavior on extraction, but Ark was not honorating it; this has been recently fixed in 015bdfd1
The same problem exists also on compression: if i right click a file on dolphin and run the "compress" action, a new tab gets opened just to highlight the new file.
This PR contains a first attempt at solving this problem, by making Ark following the same setting also on file compression. I guess the settings should be renamed and the settings dialog may need some wording change, if the settings now affects both extraction and compression.
