Build info improvements

Add a few nice touches to the build info provided on the deployment page.
Namely:
 - search for success/failure strings and colour the tag appropriately
 - make tag a hyperlink if it ends with a valid https? link
I mean they might want Integration:Passed and Integration2:Failed with appropriate colouring. Rather than only being able to indicate one happy/unhappy state. Maybe I'm making it overly complicated - but that seems like a relatively simple case to me.
