Browser: Add output styles to JS source printed in the console

Browse source 
This patch uses the new JS::MarkupGenerator to stylize all of the
source code and runtime values printed in the console's output panel.
This also does away with the Console's global style sheet, as all
styling is handled by the MarkupGenerator and the System Palette.
