Updates llfloatergroups to be a lot similar to upstream
- Adds LLFLoaterGroupPicker::removeNoneOption and changes LLFloaterGroupPicker to use modern style callback
- Switched from using per ui xml string for the none entry in groups to the strings.xml one, updated and cleaned existing translations to use this.
- Changes LLFLoaterGroupPicker into an instance tracker by id, because it was already acting like one.
