Reduce number of warnings

[k-dominik]

On a quest in reducing noise in tests, and in ilastik in general I've tackled most warnings issued by dependencies. Warning count went down from 188 to 24 when running the tests.

Warnings removed:

• numpy:
  • DeprecationWarning: The binary mode of fromstring is deprecated
  • FutureWarning: Conversion of the second argument of issubdtype from dtype to np.generic is deprecated. In future, it will be treated as np.object_ == np.dtype(dtype).type.
  • DeprecationWarning: elementwise == comparison failed; this will raise an error in the future.
• h5py:
  • H5pyDeprecationWarning: dataset.value has been deprecated. Use dataset[()] instead.

I'm doing the same in the other repos while I'm at it. Now it's easier to concentrate on our own warnings...

btw. numpy.array_equal (and it's sister numpy.array_equiv) are awesome, didn't know them before. Those functions eat almost anything

Some heroic work there. I like less pollution in my logs =D

I'm closing this and will do a cleanup for both ilastik + lazyflow once the repos are merged. It's nicer that way imo
