Use noarch build platform

[hdoupe]

This PR makes some changes to the CCC build configuration files:

• Only build for the noarch conda channel which means that one package is built for all non-arch linux operating systems.
• Build for all python versions.
• Hard codes the CCC version number. This should be updated for each release (unless the automatic version updating logic is not re-instated).

CCC can be uploaded via:

export CONDA_TOKEN=your_anaconda_token
conda config --set anaconda_upload yes
conda build conda.recipe/ --token $CONDA_TOKEN --user pslmodels

Latest commit registers the pytest marks (i.e. pytest.mark.local) per py.test 4.5.0.

Test failing should be ok with work in another PR. Going to merge this to master then into that other branch.
