Remove all group information from ModuleDetailsDTO

See merge request !142

As it turns out, some ModuleDetailsDTOs cannot even serialize because of
the immense amount of data that has to be serialized (over 256KB).
For now, we lower this footprint by passing a much smaller block of
information on student groups back to clients.

Resolve "Student Groups non-null Module"

Closes #131

See merge request !140

Lower edition details footprint

See merge request !139

Additionally, remove one from the StudentGroupSummary.division field, as
divisions might very well be null.

EditionDetailsDTO is supposed to contain all relevant information for a
single edition. However, in preliminary testing we found that this might
be a bit too much.

The number of roles could easily become so large that a maximum of three
editions could be transferred over one request.

Change the development mode security for people

See merge request !137

Change the RoleDetails in Editions into RoleSummary

See merge request !138

This should help reduce the data footprint of getting EditionDetails
objects. Currently, in running Queue, getting 3 EditionDetails objects
is enough to go over the data package limit.

Also bump the Librador version to no longer export the data field from
View DTOs.

This change allows UserIDs to be sent along with an API request unlike
before. It is now no longer ignored and APIUserDetails and
APIUserDetailsWithPerson are output in the right situations.
