Add new member

[mirdaki]

A new member can be created with any amount of a member's data (as described here) as long as a primary key is included and found to be unique in the database. If there is a duplicate, send a failure message. Any information not provided will be either empty string (if string) or false (if boolean). Either an officer, bot, or request through the club website has permissions to create a user (need to create some limiter to avoid bad actors).
