getToolByName(portal, 'portal_skins').REQUEST: AttributeError

Allow python's cryptographically secure pseudorandom number generator for usage in restricted python and use it where it makes sense.

This also change the API of `Person_generatePassword` which no longer allow to control the number of letters and numbers.

/reviewed-on !847

This script no longer allow to control the number of letters and digit

Using same method as python 3.6's secrets module and a bit longer token
that what python currently recommends, since we were using very very
long tokens until now (so that it does not look like a "regression")

- use system random
- generate longer password with a larger space

API change in an incompatible way, it's no longer possible to control
the number of alpha and numeric. This was reducing a lot the number of
combinations, so it's better to break so that callers stop generating
too weak passwords.

to make the difference with other fields more visible

If we rename a script used as external validator, we don't have way of detecting that this script might be used, so add to the "static checks" a check that for every field referencing an external validator, this validator can actually be traversed.

Check that script exists.

Like a real-world user.

__ac_name & __ac_password are only useful to get a cookie, so only use them
when the test is actually expecting a cookie.
