remove set_interactive gtk check (fix #185)...
remove set_interactive gtk check (fix #185) It was unclear why the function check_gtk() was added in the first place, but plt.show() blocked when using "ipython -gthread" without the "-pylab" also, I just want to note here that users will still experience blocking behaviour if they use e.g "ipython -gthread" but their matplotlib is set to some other backend by default (say "WX").
