Typo in synth module name

[d.healey]

This is a breaking change but one that should probably be corrected.

Scriptnode Synthesiser is listed as Scriptnode Syntesiser

And Syntesizer Group is spelt with a Z instead of an S. I think it would be better to make the naming consistent for both.

@d-healey hmm yeah - it's been that way for over 2 years....what is that fella who wrote this thing doing?
