improved file-open-dialog with preview

https://musescore.org/en/node/57886 asks for a preview feature in Windows explorer.
But what about a more comfortable file-open-dialog, that is similar to the recent-files dialog, but builds up previews for all files in the current directory.
Maybe this should be an option, because it might cause a long delay if many files must be handled.
Also a detailed-list-view might be interesting, showing the properties of the files as extract of the main score properties (tbd. what this will be...)
