I think this is because of the new complex_plot module, which I think I
positively reviewed, so this is my fault. To resolve this ticket, make
that import sufficiently lazy. Also, make a doctest that verifies that
numpy is not imported when Sage starts up.

Comment:
I'm not going to judge whether numpy imports are still an issue or not,
but in any case the patch needs to be rebased:
