randomly generated passwords must obey some constraints

[singuliere]

The password constraints of security.py require at least one digit,
one lower case, one upper case and one special character.

Fixes: #518

The generated passwords can be verified with

import random
import re
import string

_user_password = re.compile(r'^(?=.*[a-z])(?=.*[A-Z])(?=.*\d)(?=.*[^A-Za-z0-9]).{8,}$')

def t():
    specials = "@$!%*?&-_"
    random_pass = "".join(
        [
            random.choice(string.ascii_uppercase),
            random.choice(string.ascii_lowercase),        
            random.choice(string.digits),        
            random.choice(specials),
        ] +
        random.choices(
            string.ascii_uppercase
            + string.ascii_lowercase
            + string.digits
            + specials,
            k=16,
        )
    )
    if not _user_password.match(random_pass):
        print(random_pass)

while True:
    t()
