Attempt to get it building with Mingw again... builds but crashes. Fix building DLL without HTML widget support... Mingw is missing required headers. Moved wrapper functions into the main source file so it will export the APIs even if unsupported. Removed debugging code from XBrowseForFolder.cpp because Mingw does not support it.
