Changes

**** Facebook uses some JS to add rows to text areas when you hit the end of the available space. It feels nicer than a scrollbar because you can see all of what you typed -- the height of the text area just grows and grows as you need it. It would be great to have 'resize' property values that allow the browser to auto-grow a textarea as a user enters data, e.g. 'grow-horizontal', 'grow-vertical'. 'grow-vertical' would emulate the current behavior that FB does with JS.(note from fantasai - this is the behavior you'd get with fixed min-height and auto height, so CSS can do this already if HTML doesn't get in the way)
