Title: Improving performance by batching the parsing of HTML for all the lines

I've batched the parsing of the new lines to a single call to WebKit. In my tests it makes parsing go from 5ms per layout run to only 0.5ms.

Also removed the timer after each keystroke, which seems to make typing a lot much better, but I suppose a better fix would be required for that.
