Visibility warning solved

Ok, I was getting all those nasty visibility warnings on my compiles.

Irrlicht is not using the __attribute__ ((visibility("default"))) to make things public when we set the global -fvisibility=hidden but what we can do is compile on XCode Irrlicht with -fvisibility=default and -fvisibility=hidden and DO THE SAME ON OUR CODE THAT USES THE LIB

So, all I had to do is to add:

On my GCC flags.

-fvisibility-inlines-hidden

Done! Linking times are not great!
