terminatorx: update to 4.2.0.

4.2.0

A new sinc based interpolator that improves resampling quality
quite a bit, if you prefer the old aliasing artifacts a new
configuration option allows to switch back to the old linear
interpolation.

Updated the artwork a bit with a “Tux under threat” theme (yes,
that is another Public Enemy reference) – the source code based
label was really dated.

And the usual minor bug fixes.
