PHP 7 support

[ghost]

Both plugins cherry-plugin-wizard and cherry-theme-wizard produce an error 500 if the PHP version is 7.1.12. With the old 5.6.30 version everything works fine. As PHP 5 is out of active support since a year and security updates ending December 2018, this should be fixed as soon as possible please.

Are you other plugins outdated, too? I bought Monsteroid 2 and this comes with a lot of stuff from you guys. If none of them is compatible with 7.1 the hole theme is useless for me.

Edit: It is working with PHP 7.0, too, but like version 5.6 this version is outdated and security support is ending soon.
