jumbotron h1 inherits color which overrides text-success, text-warning, etc

Created by: ShaunR

.jumbotron h1 sets color to inherit, i'm not really sure why it would need to do this but the problem is that if you try and set text-success, text-warning, text-info, etc on the h1 it fails to set the color because of this. I know i could probably simply wrap the h1 in a div with a text-* class but that's extra markup that i'm thinking we can avoid?!
