revert change
Do some type checking in ask(), see issue 2322
Add test for issue 2322
Update tutorial.ru.po & remove fuzzy marker (issue 3526)
Theano _print_Derivative uses theano.tensor.Rop
_print_MatrixSlice -> theano.Subtensor
add theano_simplify to test_theanocode. fix deriv
BlockMatrix -> theano.tensor.join
block_collapse handles inverse, transpose.

Also uses bottom_up instead of top_down
remove incorrect block_collapse inverse test

1890: quartic: send Poly and raise error for some symbolic quartics

In the Euler function for computing quartics, a raw Expr was being sent
to roots and that raises an error if the equations is not univariate;
this is circumvented by sending a Poly in x.

If p is not known to be zero and is not a number, then an error is
raised since the result depends on whether p is zero or not.
