Adds a toggle to the filter menu for outliner synced selection. Enabled by default, this ensures selection is synced between objects, bones, and sequences. An active outliner element theme color is added to indicate which element is active. Synced selection is controlled on the operator level. Each operator that modifies selection for objects, bones, sequences, or outliner elements needs to call the respective ED_outliner_select_sync_from.. function to tag outliners to be synced. Syncing is done lazily on outliner draw.
