Honor User Settings

[leviwilson]

Description

When the page is reloaded, though the data is in localStorage, it didn't honor which style was selected. I've modified it so that on page load it will load your last selected style.

Additionally I've added the internalScale as a saved setting as well that is honored when your page reloads.

It still has an issue when you first save a new style from the dialog (you have to do it twice before it re-paints?) but I can look at that later.

Hi @leviwilson I'm really sorry for having missed this PR - it must have got buried under a massive pile of github notifications! I don't have a laptop available at the moment, but will hopefully look at this in about 3 weeks time.
