Title: FIX spectral clustering test error in OSX and ADD spectral embedding to sphere examples

Following @satra's suggestion in #1461 to use a more proper affinity matrix to avoid possible test failure.

Add spectral embedding to manifold example included in #1385.

@ogrisel @vene Would you please try whether this fixes the issue on Mac OSX 10.8? I do not have a mac handy :(
