[BugFix] open_plugins allow more than one entry with a plugin / parameter
you should be able to have multiple parameters to a single plugin
you can do this from outsid the plugin, but not from within the plugin
this makes it possible to have several entries with the same
plugin and a different parameter for each entry
it now also updates the name of the entry to the name of the parameter
instead of the name of the plugin (unless user edited it)
