I'm having problems running HXCPP (https://code.google.com/p/hxcpp/) dependent haxe IOS builds on Mac OS X "Mavericks" (XCode5-DP2 installed, running openfl-tools 1.0.8, so using G++). NULL references have to be removed. This diff removes all the build-breaking errors, though it's a big hacky guess.
