1) add OpenURIVia support.
2) reimplent DispatchContent so we ask the listener if it can handle the content. Then when (if) we find
a content listener that can handle it, call DoContent.
3) if we can't find a content listener, go to the registry and try to find a registered content handler.
This part isn't finished as eventually i need to be going to the category manager instead of forming
the progid for the content handler myself.

define and implement nsDocumentOpenInfo. Implement uri loader::OpenURI. This is the first pass at
my implementation it isn't complete and it doesn't use the registry for getting
protocol handlers and content handlers yet...but it's a start
