windows build fixes, 3 methods deprecated

I saw you were busy with the imagick extension, so I tried to compile the current git head on Windows with PHP 5.6.0RC2. I always compile without the deprecated methods and I had to exclude three more methods.
Besides that on several places the definitions were not at the top of the block, so I had to fix that as well.

I never compiled with the deprecated methods, so please check if my corrections are OK. Especially this addition was not checked by me:

	IMAGICK_METHOD_DEPRECATED ("Imagick", "radialBlurImage");
