Adding a z-index to pipeline-history build cause popup.

The popup was going under the header when we have only 1 instance of pipeline run with more than 2 materials in the build-cause popup. I'm assuming that the bottom limit was the footer and hence the popup was moved up. Adding a z-index:5000 makes this popup appear over the header.
Removing stage bar from VSM for instances which has not run atleast once.

This is done so that we can move the message up and because of the multi line message, it takes up a lot more space than it was allocated before. Also, my other comments are mentioned here: https://github.com/gocd/gocd/issues/540#issuecomment-57443075
