include the core plugin files on the login page

[gthayer]

Issue: #129

Fixes the missing function error by including the WordPress core functions. I am not clear why newer versions of WP are breaking, but the root of the issue comes down to the plugin firing the is_plugin_active function before WordPress has loaded it.

ping @pitbulk
i hope it's fine to ping you. it would be awesome if you fine some minutes to review the open PRs including this one. the plugin works super fine for us. yet, we hope it does still work in the future (with more recent wordpress versions), hence taking a look on this would be very much appreciated

Yes please merge this PR, we need this fix for upgraded version where it is breaking.

I've filed a similar PR to address where the function does not need to exist and instead relies on the active_plugins option:

• Fix Undefined is_plugin_active function #141

This fixes the issue with:

PHP message: PHP Fatal error:  Uncaught Error: Call to undefined function is_plugin_active() in /code/wp-content/plugins/onelogin-saml-sso/php/functions.php:108

Hope this helps!
