[PlanetCCRMA] updated: ZynAddSubFX, added: PVC

[Fernando Pablo Lopez-Lezcano]

* updated zynaddsubfx to version 1.0.9
* added Paul Koonce's PVC version 3.0-1 (Phase Vocoder package). Note: I
  had to rename the "filter" program to "pcvfilter" as it conflicts with
  the filter program of the cleanfeed package under 7.2 and 7.3. 

[I have Tapiir 0.7.0 on hold, it appears not to work for jack yet... I'm
waiting for a fix to be posted]
