Added: VST Plugin support. Add and configure plugins via Configuration Editor. The plugin's architecture has to match the OS architecture, so most people will need 64-bit plugins. The subdirectory plugins is offered to put plugins into, but they can be opened from any directory with sufficient permissions.

Fixed: When trying to add a high-pass filter in the Configuration Editor, it was instead configured to be a low-pass filter.
