Tutorial: Minor fixes wrt addition of reset button. * Swapped Reset and Save button so Save is on the far left. (I find it is a different, more passive action than the other 3, so it belongs on its own. Also it's grey most of the time so it looks better separated). * Reset button now activates the Save button (as it has modified the text box), in the same way that directly editing the text does. * Added a bit of padding under the text box, because there was none before and it looked bad.
