Fix for:
http://code.google.com/p/thtmlviewer/issues/detail?id=251

Workaround for issue with TCustomStyleEngine.UnRegisterStyleHook in Delphi XE2.
Add functions for displaying source-code.  I use this for debugging but it's nice for other stuff too.
Add TFileConnection functionality for listing dirs as HTML.  Something similar can be done with Gopher and FTP if desired.
