Disabled appearance of SyntaxEditor

Hi Alex,

You could set the control's BackColor to another color when it's disabled.  However when testing that just now, I noticed it wasn't kicking off a repaint.  So you'd have to do this until the next build, after which you can remove the Invalidate() call:

editor.Enabled = false;
editor.BackColor = Color.Silver;
editor.Invalidate();

The BackColor should be Color.Empty when you want it to use the default coloring set up via highlighting styles.
