AWS's VDB set up manual

[InfiniteRegen]

1. set password for root. (caution: you should change not only password for localhost but also all of root's password)

2. then type this two lines ( preventing data integrity crushed)
   __# python manage.py migrate vdb zero
   __# python manage.py migrate vdb

3. because Current version of mysql on AWS doesn't support length of 16 for userid.
   we should replace md5 functions used for userid with any hash function that generates less then 16 bytes string.
