Add missing HTML element slashes to jQuery calls

Not sure about the space. I love to have it for the sake of readability.
I find that much easier to read. Our code base currently uses both, a
lot without space but also a lot with space. Can we agree on the space?
Otherwise I will remove it everywhere.
