[DSSI] VST getChunk/setChunk support completed!

[Андрей Д. <and...@gm...>]

Hi Sean!
Hi All!

I've recently managed my patches to work properly! Now rosegarden saves all
chunk parameters of vst plugins in rg file and restores them :). I hope that
there is some interest in such functianality, so I can send those patches to
you - may be they become an official release of dssi, dssi-vst and
rosegarden.. :)

WBR, Andrew.
