BUG FIX: state_updates should be initialized in MRG_RandomStreams.__init__ to
prevent different random number generators from sharing state.
Changed comment.
Moved initialization of RandomStreams member variables to __init__
Removed all class-member initialization from MRG_RandomStreams, RandomStreams
and SharedRandomStreams (and added associated unit-tests)
Recipe for copying random state from one theano graph to another.
Added unit-test for transfering random states between theano graphs
Added blas GTX460 timming.
Better error message.

Misc2
Use other impl. of OrderedSet to prevent mem. leak

Previous implementation resulted in memory not being freed,
as exhibited in particular on theano/sandbox/cuda/tests/test_memory.py.

The version for older Python, as well as the new one, appear to work
correctly on that test.
Changes after code review.
