Better admin control for pupil management

There's a couple of things that would really improve the admin side of managing a school using noteflight:

• Ability to search for a user in manage members. Currently having to click 'more' multiple times and scroll down through 300+ users is quite annoying.
• Add a way to assign groups/classes by csv upload. Had to manually assign members to each group for each class in the school of which there's a lot. Will have to do this manually every year (although realistically would just look for a different service rather than do that every year) especially considering it suffers from the above point of having to click more and scroll though a list of usernames rather than having them all loaded in instantly or being able to search.
