Added a tag list to exclude items from the credits list. The list is saved with the plugin preset if used as a session plugin. Just use a unique term out of the item's name, such as 'DebugConsole" to exclude 'perfectbloo.DebugConsole.1 (CC BY-NC-ND)' for example.
Added the option to generate a one line output, useful e.g. for adding credits in the caption of screenshots
