This allows configuring the block_quote.colors.prefix attribute to configure the color of the block quote prefix (which defaults to a vertical line). If this key is absent, the color will be the same as the block_quote.colors.foreground one.
Along with this change I changed all the built in themes to have a prefix of the same color as the slide title except for a couple of light themes where I had to pick a different one.
