[Xon] Password Tools 3.11.1

• Require XenForo 2.2+, drop XF2.1 support
• Actually implement cron to prune the pwned password hash cache. Old entries where already being ignored, so this will hopefully just reduce MySQL table bloat
• Fix denial of service attack by preventing too long password which can trigger factorial number of brute force password checks when using Zxcvbn
  • Update new install option defaults to more recommend values:
  • Enforce password complexity for admins
  • Enable "Length check by default, and set the "Minimum length" to 8
  • Enable "Pwned password password validation" by default

• Switch back to upstream bjeavons/zxcvbn-php library as it should be fully php 8.1 compatible.
• More 32bit php fixes, Thanks to @NamePros

• Fix edge case where 32bit php would incorrectly report a very strong password was weak due to bad float to integer truncation.
• Recommend ext-gmp (aka php-gmp) for optimized binomial calculations, which requires php 7.3+

• Dramatically reduce redistributable size by trimming unneeded files
• php 8.1 compatibility fix

• Reduce queries when triggering forced email 2fa
• Prevent rare DuplicateKeyException when forcing email 2fa and multiple tabs are being used

Thanks to @NamePros for sponsoring this update.

• Update compromised password alert text to be less awkward
• On updating passwords, remove any compromised password alerts to avoid user confusion
• Add "Force email two factor authentication on compromised password" option (default disabled)
• Add "Pwned password minimum count (soft)" option.
  This allows a user to change a password to a known compromised value which is under a given number of known hits. This still generates compromised password alerts

• Force global namespace for functions which are known to be optimizable to bytecode in php, or known global functions to avoid a current namespace lookup for the function.
• Add "On login; alert the user if they have a known compromised password" option (default enabled)
• Add "Minimum time between triggering compromised password alerts on login" option (default 24 hours)
