Ixion: Minor fixes to Gutenberg implementation, including:

* Correcting caption size.
* Add space next to file button for RTL languages.
* Update selectors for buttons, custom colours.
* Make sure bullets are centred when widget blocks are centred.
* Remove empty selectors.
* Update comments widget to better match theme's comment styles.
