Rebalance: Minor fixes to Gutenberg implementation, including:

* Update drop cap positioning.
* Add italics to verse block, to differentiate it.
* Update selectors for button blocks, for better custom colour fallbacks.
* Update colour selectors, to account for :visited state.
* Update latest comments block to look more like theme's comments.
* Correct table header background colour; remove unneeded borders from table in editor.
* Make sure bullets are also centred for list-based widget blocks.
