Veikko Sariola dc88b885e9 Fix warnings when built using nasm.
Nasm gives warnings about labels without colons in the end; these were particularly prevalent in struc members: ".size" has be ".size:". Nasm also wasn't happy with extra trailing commas when calling macros.

; warning: crashes ahead. Now that the bpm could be changed and even modulated by other
; signals, there is no easy way to figure out how many ticks your song is. Either
; allocate some extra memory of the output just in case or simulate exactly how many
; samples are outputted. Here the triplets are slightly faster than the original so
; they fit the default MAX_TICKS that is calculated using the simple bpm assumption.
