Title: sympy.interactive ipython print extension. Fix mathjax rendering in the ipython notebook.

The mathjax rendering does not work in the notebook with sympy 0.7.2rc1

There are two problems.
Change can_print_latex to _can_print_latex since that is what it is called now.

Needs to import sympy to compare with sympy.Basic. This was removed when moved to sympy but is needed.
