Title: #319 Fix bug in SBSersic kmax calculation

This is primarily a fix for the ringing that Rachel was seeing in some devauc images convolved with an airy psf. I tracked the bug down to the calculation of the maximum ksq in SBSersic. (This was my error as part of my optimizations in this class -- Gary is blameless here.)

In addition, Reiko made the good suggestion that we should be able to draw the k-space images from python. This was already a c++ function, but it wasn't ported to the python layer. So I added that as `obj.drawK(...)`.
