features like set paragraph style, set list type, indent, etc.  I'm sure there's holes in my
implementation that these high level features will make obvious.

2. I've factored a lot of utility methods from several modules into nsEditor as public static methods.
This makes them easily accessable to all, and will help Joe and I remove redundant methods.

3. I changed the HTML tags to lower case, and made all string compares case-insensitive.  No, this
isn't quite the right thing to do, but we don't have atoms from layout yet.  The Right Thing is for us
to reuse those atoms.
