Clearer node filter options

[poliver]

• Adds section titles ("filter" and "sort") to node filter dropdown
• Adds radio buttons to sort options, since they are single-selection
• Adds check boxes to filter options, since they are multi-selection
• Don't close the menu after each selection. This is especially annoying when selecting filters.
