Keep Empty Lines

[nihklas]

I like the formatting that superhtml provides, but I would like to keep the empty lines between some elements to better organize my html files. Right now, i find it hard to navigate, the longer the file gets, because everything is cramped together, unless I use comments.

Standard behaviour that I noticed in a lot of LSPs/Formatters, which I would also like for superhtml, is that empty lines are collapsed into a single empty line, if present.
