A convenience function that attempts to load all configured SFML binding.
This function will always call loadSFMLSystem and will call the load function of every binding that is configured. If SFML_Graphics is configured, both loadSFMLWindow and loadSFMLGraphics will be called. This function will return false as soon as one of the load functions returns SFMLSupport.noLibrary or SFMLSupport.badLibrary.
There is no variation of this function allowing for alternative shared library file names.
