Python tox based compression safety testing

Compression keywords safety tests:
==================================

In issue telegraphic#140 it was reported that some loaders crash
when 'compression', 'chunks' and related h5py keyword arguments are
specified. By running pytest a second time and thereby specifying
the custom --enable-compression parameter all tests are rerun with

   kwargs={'compression':'gzip', 'compression_opts':6}

All compression sensitive tests especially all 'test_XX_*.py::*' unit test
functions must include the 'compression_kwargs' parameter in their
signature to receive the actual kwargs list to be passed to all 'create_fcn'
function defined by loader module. In case a test function misses to
pass on the 'compression_kwargs' as keyword arguments ('**kwargs') to
   'hickle.dump',
   'hickle._dump',
or any dump_method listed in 'class_register' table of loader module or
specified directly in a 'LoaderManager.register_class' an AssertionError
exception is thrown indicating the name of the test function, the line
in which the affected function is called any function which it calls.
Tests which either test compression related issues explicitly or do not
call any of the dump_functions may be marked accordingly using the
   'pytest.mark.no_compression'
marker to explicitly exclude test function from compression testing.

Tox virtual env manager support:
================================
Adds support for virtualenv manager tox. Tox simplifies local testing of
compatibility for multiple python versions before pushing to github and
creating pullrequest. Travis and Appveyor integration still has to be
tested and verified.
