Rename io/dynamic_io_new.hpp to io/dynamic.hpp

@sdebionne suggested in #185 (comment)

should io/dynamic_io_new.hpp be io/dynamic_io.hpp really?

I think it is a valid suggestion since the current name is unnecessarily complex, may be confusing:

• new is obscure: as in new implementation or as in new-allocated dynamic memory, etc.
• io is redundant, since all core IO headers live in dedicated directory

I'd expect renaming it is safe from compatibility point, majority of the file is boost:gil::detail namespace and just this one lives outside

gil/include/boost/gil/io/dynamic_io_new.hpp

Lines 91 to 96 in 2250b71

	/// \brief Within the any_image, constructs an image with the given dimensions
	/// and a type that satisfies the given predicate
	template <typename Images,typename Pred>
	inline bool construct_matched(any_image<Images>& im,Pred pred) {
	return detail::construct_matched_t<mpl::size<Images>::value>::apply(im,pred);
	}

but possibly it should live in the detail as well.

Comments?
