Update audio/praat to latest upstream release
With this update, I'm taking the time to tidy up some bits:
- jack was not used
- configurable audio was not used (I suppose there used to be OSS / JACK / ALSA, but it's settled on just ALSA here)
- simplify the dos2unix bits (I'll report the remainder upstream)
- there are fonts for phonetics, although I don't see a difference: leave them commented-out
Release notes as always at:
https://www.fon.hum.uva.nl/praat/manual/What_s_new_.html
with new scripting commands as most-interesting-bit (in 6.1.35).
There were some intermediate releases, which didn't add anything
for us on FreeBSD.
