PHP7 compatibility

[JosiahCarberry]

A check of PHP7 compatibility yields:
For...
.../plugins/betteroptin/vendor/gambitph/titan-framework/inc/scssphp/scss.inc.php
HP version 7.0 and cannot be invoked as a function (T_STRING)
3643 | ERROR | Function name, class name, namespace name or constant name can not be reserved keyword 'string' (since version 7.0)
3756 | ERROR | 'string' is a reserved keyword introduced in PHP version 7.0 and cannot be invoked as a function (T_STRING)
4007 | ERROR | 'string' is a reserved keyword introduced in PHP version 7.0 and cannot be invoked as a function (T_STRING)

Do you plan to make updates to resolve these errors? If so, for when?
