[Bugfix/Feature] OpenPlugin and default plugins

selecting files to run is nice and all but you might not like the plugin
you can edit it OpenPlugin Viewer Plugin but instead pop it when you add
a file to reduce suprises

shortcut viewer is not ready for this so exclude it for now

Change-Id: I950599d87f47d42e8c2d59695f6583d497b217f0
adds: default plugin (if any) is selected in the open with dialog
