Plugins:

* EntryOutput is passed to CopyToClipboardService
* Modifications of EntryOutput are passed to plugins to enable actions on added fields
* PluginDatabase checks if Plugin is still installed and always updates the list of plugins (had an issue where a plugin had a request token but was not in pluginList)
* first version of QR plugin implemented
