erp5_jquery_plugin_validation: Replace jquery.validation.password .

- Do not enable on all password fields
- Allow specifying strength metter for a given field
- Allow customising password validation rules by changing properties
(allows different rules in the same page)
- Login similarity check can be done by adding login as a sequence
or blacklisted word, as desired
- No hard rules of what a strong password is, instead use a reward
system for using varied characters & character classes, reduced
when password contains widely known sequences or too common
passwords.
