Strip ANSI sequences from captured task outputs before display. #849

Some programs colorize their outputs, so before sending back the stdout and stderr to be displayed in CBRAIN, let's strip those ANSI sequences. Maybe also let's escape or delete any other non-printable control characters, such as as ^H.

sample perl script http://impson.tzo.com/~jdimpson/bin/script-declutter to interpret controls. A simple stripping Ruby snippet https://rosettacode.org/wiki/Strip_control_codes_and_extended_characters_from_a_string

With a proper gem, colors can be rendered rather than stripped https://rubygems.org/gems/ansi-to-html/versions/0.0.3, https://buildkite.com/blog/terminal-open-source-ansi-to-html-renderer
