Module(s): asaplotter, asapfitter, sdplot, sdfit, sdflag

Description: register asaplot instance to matplotlib when backend is Qt4Agg.

This enables background plotting --- leaving plotter opened after exitting
from a function you created the plot.
On TkAgg backend, this is not explicitly done, seems to be done automagically.
