ref #4257
- This is a follow on from #4257 where I updated the codestyle.
- We were outputting escaped single quotes when double quotes would be much nicer.
- Changes the HTML output from our markdown conversion (non-breaking change)
- Updated tests to match the new output
ref #4243
- Removing /lib/ from the list of things which aren't linted, as this is
all custom code
- Fixing up the two files to pass linting, erring on the side of caution
with disabling regexp rules vs fixing regexes!
