Use LaTeX to print various built-in types with the SymPy printing extension

SymPy's latex() function supports printing lists, tuples, and dicts using
latex notation (it uses bmatrix, pmatrix, and Bmatrix, respectively).  This
provides a more unified experience with SymPy functions that return these
types (such as solve()).

Also print ints, longs, and floats using LaTeX, to get a more unified printing
experience (so that, e.g., `x/x` will print the same as just `1`).  The string
form can always be obtained by using `print`, or 2d unicode printing using
pprint().

SymPy's latex() function doesn't treat set() or frosenset() correctly
presently (see http://code.google.com/p/sympy/issues/detail?id=3062), so for
the present, we leave those alone.

Currently, the printing of lists, tuples, and dicts does not work correctly in
the qtconsole.
