Allow Pickle/Unpickle of Theano function without recompiling

Add: tensor.choose and typed_list.make_list

Fixed bug wherein graph had more than one input but only one alloc and it tried to use an input without alloc as a baseline.

Change date, minor updates.

Updated local_alloc_elemwise to remove all allocs when possible and to add assert only when we cannot determine whether the shapes will be correct.
Deprecated experimental.local_alloc_elemwise and enabled local_alloc_elemwise by default.

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
