[Gnuplot-py-users] change default term on unix to wxt

[Benny M. <ben...@gm...>]

Hi,

If nobody complains, I'll change the default terminal for unix to wxt
instead of x11. The wxwidget terminal is the default in gnuplot itself for
some time.
I believe it is time to have new users in the future have the nicest
experience, users on older system can change the default in gp_unix.py back
to x11.

Alternative is not to set terminal in _Gnuplot.py, as then gnuplot chooses
it's default, so to change the default to do nothing, and only when
gp_unix.py contains an entry different from '' use that. I think I like this
alternative actually best.

I have no other systems, should people there feel defaults should be changed
for their system too, let it be known.
