Ensure password strength accepts weak passwords and rejects good passwords

[andytough]

When using
&ensurePasswordStrength=1
&ensurePasswordStrengthSuggestions=5

I had the following password rejected as not being secure enough:
5Iid5/BGaWvCqcaOwxbywg==

The following password was accepted:
password

Adding options using these did not seem to resolve the problem.
&maximumPossibleStrongerPasswords
&minimumStrongPasswordWordCount

The suggested alternative passwords were all accepted
5I!d5/BG@WvCq(@OwXByw6==
5I!d5/BG@WvCq(4OwX8yw6==
5I!d5/BGAWvCq(AOwX8yw6==
5I!d5/BGAWvCq(4OwXByw6==
5I|d5/BG4WvCq(AOwXByw6==

However, I have occassionally had the alternative password suggestions rejected.
