added infrastucture for restructure

few issues with types, missing columns and table names; nbd
added proper hash comparison for login
database overhaul, registration/login/cookie works

renamed db tables to all lowercase (canonical pg)
changed some fields/types... see init() in comments
  namely
    bytea to store salt/password
    use serial type for id (does incrementing for us)
updated login to correctly salt input, compare hashes
file server works (granted, worthless)
fixed merge
made email unique
patch login security hole, trim readme

never tell a user whether pw or username is wrong, only both
moved readme todo list to issues
