Modern settings shell folder
Adds virtual shell folder that contains items representing modern settings parsed from `%windir%\ImmersiveControlPanel\Settings\AllSystemSettings_{253E530E-387D-4BC2-959D-E6F86122E5F2}.xml`. It can be accessed via `shell:::{82E749ED-B971-4550-BAF7-06AA2BF7E836}` (in explorer). Item in folder will open given setting page in `Settings` application.
