Disable colors on SBT build output

SBT likes to output stuff with formatted colours, and Play 2.0, which now uses SBT (note play 2 and play 1 use completely different build frameworks, when deploying a play 2 app to cedar it is detected and built as a Scala app, not a play app) makes extensive use of this feature. This is nice, except when deploying, which is very often done from automated scripts, eg from Jenkins or some other CI server, or from other automated scripts, not directly from a console. It's often necessary to work with the logs in something that isn't a console, for example, in Jenkins you view the logs on a webpage, or you might be reading the logs in an editor. If you try to do this, what you get is output that looks something like this:

� Imagine stuff with ansi colour codes on it, because github kills it.

So in these cases it is necessary to turn the colours off. This is very simple to do, just pass the following argument to SBT:

-Dsbt.log.noformat=true

Thoughts? It sounds like a sensible default, being the output is piped through git.

Github is truncating the output for some reason, the remained is some samples with ansi colour codes, then this suggestion:
