Title: Add ability to blacklist students.

The action to blacklist students is now under `Admin actions` -> `List users` -> `Blacklist`. This will set the user model property `onBlackList` to true.

Please note that this doesn't bar students from signing up for trips as this is just marking a student as blacklisted.
