Cruisecontrolrb Cruise Control.rb

spec --color is great on the command line, but the ANSI color codes look like gibberish in build logs in CruiseControl.rb. Attached are a Rails plugin to convert ANSI color codes to HTML spans with inline CSS style attributes for coloring text on the builds page, and a diff against app/helpers/builds_helper.rb to do the conversion.

I was really hoping this would work as a CruiseControl.rb plugin, but the build log output is being sanitized in the view. I'm willing to rework this stuff if we can come up with a suiteable work-around, but the only alternative I could think of was to modify CruiseControl.rb itself.
