- update to 1.77.1:
* The 32-point sinc resampling interpolator was reduced to
16-point again because of the trade-off not being big enough,
and it was slightly wrongly implemented and would alias a
little bit in some cases. I'll implement a better sinc
interpolator in the future, if I ever stumble across a nice
and simple implementation. Please let me know if you have
one!

* Note transpose (block), instrument remapping (block), Cut Block (ALT+F3)
and Copy Block (ALT+F4) had issues if you had made a block selection in
the last channel/track in a pattern.
Thanks to Roz for finding this and reporting it, and sorry to all the people
