Title: merge dense and sparse coordinate descent

#861
I have added support of sparse data to the dense ElasticNet class and applied the tests originally written for the sparse version to the former dense version. Do we need additions tests?
Please let me know if this goes in the right direction. I will then update the docstrings and put some more effort in reducing duplicated code.
