MessageBar specific classes are missing in fabric.components.css 2.6.0

Building the current project results in css files without the messagebar component.

Thanks for reporting this issue and tracking down the root cause, @andikrueger. I'll get started on a 2.6.1 patch release to fix it.

We've run into issues like this before; it's frustrating when we let such glaring problems get through the release process. In Fabric 3.0 and later we'll be using the main fabric.components.css stylesheet on the component sample pages (rather than individual MessageBar.css-type files) so that we can catch these issues. We'll be testing those sample pages and requiring full documentation before merging anything in.
