Configure MSBuild task to fail on static code analysis warnings

Using Bamboo with MSBuild, the task does not fail on static code analysis warnings.

Currently Bamboo only takes into account the exit code and does not do any sort of log parsing to detect warnings. Bamboo does not detect this and continues to build. It would be nice to have an option to "fail build on warning" so Bamboo could parse out these warnings and fail the build (and even show them in the Bamboo console).
