Ordering of group participants

[Petersmit27]

Problem

Group participants are ordered in the way they are created, and can never be rearranged. This makes group creation a hassle, or leaves the user with a list of participants in a random order.

Easy solution

Participants should always be ordered alphabetically. During creation, the user can enter participants in whichever order they want, and after creation the participants are automagically sorted.

More difficult solution

Sort participants alphabetically by default, but give the user the choice to rearrange the participants when creating/editing the group.
