Scratchpad: Minor fixes to Gutenberg implementation, including:

* Update drop cap positioning and sizing.
* Add script font to verse block, to differentiate it.
* Update selectors for button blocks, for better custom colour fallbacks.
* Update colour selectors, to account for :visited state.
* Make sure bullets are also centred for list-based widget blocks.
