Title: MRG rename parameter "multi_class" of LinearSVC to "crammer_singer"

After reading issue #657, I felt like "multi_class" is a bad name for the Crammer-Singer option of the LinearSVC. Many people want to do multi-class classification. Only few want or even know about Crammer-Singer SVMs.
To avoid confusion, I think it would be good to rename the option and make a bit more explicit that this is not needed for multi-class classification.
Also, I had the impression that the Crammer-Singer SVM was not tested that much, so I tried to come up with some tests.
