Move return types to separate file
Place linux builds in correct 32/64 bit dir
Print file types after logging initialized

Log file types to log, not stdout
Better error message when preset fails to load

Indenting
Expose VST unique ID

Add some more application tests

Now we can almost trust the integration testing! Also cleaned up some verbose
