Removed private API use that was causing AppStore rejection

Pavel Kanzelsberger to SDL

I tried to submit a SDL application to the Mac AppStore and it got rejected because SDL cocoa is using a Private (non-public) API. Problematic part is here:

SDL_cocoaevents.m

@implementation NSApplication(SDL)
- (void)setRunning
{
    _running = 1;
}
@end

Symbol _running in NSApplication is private and shouldn't be used. Any ideas what could I do about this?
