VST to host sync

Browse Source 
This patch should bring VST to host synchronization for LMMS.
 (e.g. for plugins like dBlue Glitch, TAL Filters).

Synchronization is done via shared memory, missing song time
positions are reccalculated and added to PPQ position sync values
(SHM - common input interface for sync of all VST plugins)
