Steps:

- Creat the database file at: src/contents/kcfg/
- Inherit from the class "PluginBase" when creating the plugin class that will wrap the LV2/LADSPA library or any other necessary for the audio processing
- Make the call "settings->disconnect();" in the plugin class destructor
- Override PluginBase's reset method and call inside it "settings->setDefaults();"
- Create the plugin class instance inside "EffectsBase::create_filters_if_necessary()"
- Pass the plugin instance pointer inside "EffectsBase::getPluginInstance(const QString& pluginName)"
- Create the plugin qml file inside src/contents/ui/
- Add the qml file to "src/resources.qrc"
- Create the plugin qml window instance inside the function "createPluginStack" defined in the file "src/contents/ui/PageStreamsEffects.qml"
- Create the plugin preset wrapper inside "Manager::create_wrapper"
