first stab at microshaft wangblows support.
Still untested.
* CheckDirExist now returns correctly if file is given
* Replaced dummy typedef with int parameter
Actually got a dev environment up!
* Added xdg-open replacement
* Fixed method calls
TODO:
* Check if this code doesn't crash
* Figure out what to do about the last error - mode_t doesn't exist on
windows, so this can't be compiled. Fix Platform.hpp?
Replaced mode_t with unsigned, so libgtorrent compiles in windows and in
linux.
