Currently, the folders are shown with a filled icon. I'd like to replace them with the icon showing an outline folder only. This new icon is only available in the latest version of the icon font - you'll have to update that one first (see linked issue).

Please make the following changes:

• replace 025_folder with 118-folder-l everywhere the former is used currently. Folder will show with their outline by default.
• use 119-node-folder-l for a configuration node folder. We're currently using a folder icon (025_folder), because we've found that the configuration node folder icon 045-node-folder was too unclear. With the new outlined, variant 119-node-folder-l I expect this to change, however.
