Merge branch 'win64-vst'

* win64-vst: VST support layer: fixed non-working 64 bit VST plugins VST support layer: added 32 bit VST plugin support for Win64 Win64Toolchain: added 32 bit compiler configuration ZynAddSubFX: use new RemotePlugin::init() method RemotePlugin: added support for running remote process multiple times
