Invite multiple people through e-groups

[plourenco]

Manually adding multiple participants can be arduous, especially for a group activity that could generally be solved by inviting all the participants of an e-group. This issue suggests the implementation of multipass (or local) group based participants.

There's the usual privacy issue that comes with allowing someone to expand a large group whose members the person may not be able to see otherwise.

A good alternative is to not add individual participants via group but just share the generic response link with the group e.g. via email...

Hey @ThiefMaster - could this be done without visibly expanding / exposing the list members? For other purposes (e.g. the "follow-up enhancement suggestion" in #472 ) it might still be worthwhile to make the recipients info available to Newdle.

And even without exposing the members, scheduling could be helped by aggregated availability info, indicating times where 100% of the members are available. And yes, there ought to be a limit to the number of members when determining the availability... (cernbox-users!)
