rememberSkinTone property
Remember the last skin tone the user selected.
When true, the tone chosen via the long-press picker is persisted (in
SharedPreferences) and re-applied as the default for every
skin-tone-capable emoji in the grid, recents and search on the next
launch. Selecting the base (no-tone) glyph clears the remembered tone.
When false (default) the base glyph is always shown, which is the
previous behavior.
Implementation
