Error with PHP7.

Hi there,

Thank you for your great work on Piwigo.
I got this error accessing profile.php:

Deprecated: Function mcrypt_get_iv_size() is deprecated in /home/.../public_html/piwigo/plugins/Subscribe_to_Comments/include/functions.inc.php on line 579

Deprecated: Function mcrypt_create_iv() is deprecated in /home/.../public_html/piwigo/plugins/Subscribe_to_Comments/include/functions.inc.php on line 580

The encrypt/decrypt methods could be rewritten using OpenSSL if available https://paragonie.com/blog/2015/05/if-you-re-typing-word-mcrypt-into-your-code-you-re-doing-it-wrong

Keeping in mind that old share links must still be decoded with mcrypt (the new links encrypted with OpenSSL must have a distinct prefix).

Unfortunately I am done with PHP.
