Update imageio recipe for v1.5

[almarklein]

Now that freeimage is available in the main channel (proposed in #335, implemented in #362), the recipe for imageio becomes straightforward.

I verified on Windows, OS X and Linux that imageio picks up the freeimage lib provided by the conda package.

Note that imageio does not depend on a specific version of numpy; is there a way to provide that info in the recipe, to avoid having to build the package against multiple numpy versions?

Pinging @ilanschnell about it.

It should be fine as is. If you wanted to build against a specific version of numpy you would have use the the numpy x.x feature. When you build this recipe, does it end up with a dependency on a specific version of numpy, or just a general dependency?

AFAIK it builds against a specific version, but I might be confusing something. To be clear, imageio does not require a specific numpy version. (sorry for the late reaction, I've been ill)
