Feature: horizontal scrolling in shinyDirChoose

[sneumann]

Hi, I am using shinyDirChoose to browse and select stuff from filesystems with nesting (10-20 levels) and filenames (20-60 characters long) where the standard layout in shinyDirChoose will just cut off if things don't fit into the boxes. I'd love to have the option of horizontal scrolling in both the Directory-tree and Content Panes. Yours, Steffen
