Subject: Assure that the view properties of a column view are always stored in the folder... 
X-Git-Url: https://cloud.milkyroute.net/gitweb/dolphin.git/commitdiff_plain/253c3c87a8a1b6418125f6fd90864c8daa76a0c1

Assure that the view properties of a column view are always stored in the folder represented by the first column. It is assured now, that all columns use the same view properties. Although one reason is because of technical 'restrictions' (KDirLister properties like 'show dot files' are applied to all sub directories too), I personally think it also makes sense from a usability point of view.
