speedy: repair A10 db-notice-multiple parameter

Per request at WT:TW.
config: make helptip links open in a new window

So pref choices aren't lost when these links are clicked.
tag: convert tag-specific prompt dialogs into subgroups; post at WP:PNT when relevant

- The {{not English}} and {{rough translation}} tags ask the tagging
user to list the page in the appropriate section of WP:PNT. Timtrent
requested at WT:TW that this functionality be added to Twinkle.
- Most prompts for article tags are now implemented as subgroups, to
provide a smoother experience for the user.
