Getting psake to throw errors rather than write them to output...

[Jeffrey Becker]

I'm working on a Team Foundation Build template which will invoke a psake build rather than going through the mess of workflow xaml.  It would be useful if I could get invoke-psake to throw errors which would propagate up the stack rather than calling write-coloredoutput with a message.  My current m/o is to add an optional argument to invoke-psake.  Is this something where a pull request would be likely to be accepted?
