Luis Pedro Coelho ff0b315110 RFCT Simpler code for initializing array 
Also, replaced skimage.measures.histogram by np.bincount.

Both changes were suggested in the pull request discussion by Juan
Nunez-Iglesias (jni):

Luis Pedro Coelho f81fbf5b25 ENH Faster perimeter computation 
Measured a 30% speedup on a 640x640 image. Fundamentally, this makes
fewer passes over the image; so it should never be worse that the
previous implementation.

Luis Pedro Coelho 6ebc43bad8 ENH Add imread io plugin 
This relies on imread (https://github.com/luispedro/imread) which
supports a few microscopy formats otherwise hard to read (LSM and
MetaMorph STK) as well as basic ones.

Luis Pedro Coelho 30b4ff2274 Fix freeimage_plugin.imsave 
Previously, the plugin perfomed a copy of the bitmap's pixel memory
instead of mapping into a ndarray. This fixes it. Also, it saved images
rotated by 90 degrees as it didn't convert to freeimage's internal
format.

Copying less also makes imread visibly faster.
