feat(document): add_drop_shadow_to_selected mutator

Browse source 
Append a default drop-shadow effect (CSS-style 0 4px 8px
rgba(0,0,0,0.25)) to the selected node — the building block the
property panel's 效果 "+" action will call. Guarded on a real,
editable selection like the sibling set_selected_* mutators.
