fix gh-2204

Allow Pickle/Unpickle of Theano function without recompiling

Add: tensor.choose and typed_list.make_list

Mixed

Change date, minor updates.

It was making a test crash with python 3.3

This was causing a test failure in python 3.3.0, as cmp isn't a
built-in function anymore.

This allow to free the temp memory with the old linkers.

support: no need to re-optmize when unpickling theano function. added a new option reoptimize_unpickled_function=False
