Add configurable toolbar icon sizes

Introduce a toolbar_icon_size setting (1=XS..5=XL) with serde default and Default impl. Add UI in settings panel to pick XS/S/M/L/XL and save on change. Make toolbar height and toolbar button/icon sizes adapt to the selected preset (including small icon buttons). Bump package version to 0.4.2.
