FlxTilemap buffers are not updated on camera resize or replacement

Nicely demonstrated by a sample project from @jscott1989: https://github.com/jscott1989/camera-test

I think there is not a easy solution but call tilemap.updateBuffers() manually on changing cameras.

Because FlxBasic is not notified when its main camera changed:

private function get_camera():FlxCamera
    {
        return (_cameras == null || _cameras.length == 0) ? FlxCamera.defaultCameras[0] : _cameras[0];
    }

I mostly solved this locally, it involves adding a few new FlxSignals for certain "camera events". I struggled with adding proper unit tests for this though..

Eh, I didn't mean to close this just yet.
