more types for sage_input: vectors, matrices, etc.

[sagetrac-cwitty]

I'm attaching a patch to increase sage_input support. Newly supported are floats, elements of RDF and CC, vectors, and matrices (sparse and dense). I also added some new features to sage_input for handling these new types, and fixed a bug in matrix_modn_sparse that was exposed in the process (sorry, the bug fix really should have been a separate patch).

This patch depends on #2898 (and hence indirectly on #3938).

I've looked over the patch and it looks reasonable. Doctests pass on 3.3alpha3 for all (nontrivially) touched files. Positive review.

This does depend on someone reviewing 2898, though.

This fix depends on #2898 getting a positive review and getting merged.
