Version 2.3

[michaelryanmcneill]

Changes include:

• Implementing a fallback option for the "Shibboleth Attribute Access Method". For example, if your web server returns redirected environment variables, but occasionally returns standard environment variables, you would want to enable this option.
  • Removing deprecated create_function() from use.
  • Bumped minimum PHP and WordPress versions to 5.6 and 4.0 respectively.
  • Greatly improved the handling of managed fields and cleaned up options-user.php.

Resolves #69 and resolves #70.
