Title: WIP: merge sparse and dense SVMs

This branch merges support for sparse matrices into the vanilla SVM classes. It's not completely finished yet.

I propose a new convention for the SVMs: they support sparse data in predict iff they have been fit on sparse data. This is different from the current behavior of `svm.sparse.*`, which is to convert dense sample arrays to CSR matrices.

To do:
* merge the tests
* update the documentation
