recording: Escape custom poll answers in gnuplot file

 Try to improve commit message. Nothing has changed in the code.

 Process converting of message from json on a different thread to protect the redis sub actor from
 dying when exception occurs due to invalid message.

 - process converting of message from json on a different thread to protect the redis sub actor from
   dying when exception occurs due to invalid message.

Custom poll answers were previously printed into the gnuplot control
file directly, between double-quotes. As a result, if a poll answer
contains a double-quote, it could cause a syntax error in the gnuplot
script, or worse.

Gnuplot accepts standard C-style double-quoted string escapes, so I can
just use ruby's "inspect" method to generate a safetly escaped string.

Note that within the string, % still has to be escaped separately
(doubled) to avoid issues with the string formatting. As well, I have
disabled "enhanced" mode which allows using special characters for
formatting commands.
