* LVSL: call waitpid(...) when closing plugin - fixes zombie processes

Browse Source 
* VST-effect: finally made VST-effect plugin work
* core: when rendering from command-line, only create a QCoreApplication - needs further work
* Singerbot: integrated patches from William Steidtmann <billstei/at/hbci/dot/com> which makes Singerbot at least compile - doesn't seem to work yet though
