Subject: [PATCH] Fix Redirector config escaped strings

When printing out the configuration JSON, the Redirector extension
expects regex escapes to be escaped, themselves. So `\` becomes `\\`.
However, Crystal treats these as escaped character also, and each `\`
must additionally be escaped, so a single slash becomes `\\\\`
