Changed nsHTMLFrameInnerFrame to hold on to a subShell that is an nsIBaseWindow instead of a webShell. This paves the way for holding different types of objects. Also gets rid of that stupid nsIWebShell interface. :) When creating the docShell use the new docShell interfaces rather than the old webShell ones.
