Deprecated has_cap usage

Hi there, I’m using this plugin on a server running php 7 and get errors pointing me to this line in reaction_buttons.php:

add_options_page('Reaction buttons', 'Reaction Buttons', 8, 'reaction_buttons', 'reaction_buttons_submenu');

Would seem this 8 is from has_cap, instead of using the roles and capabilities system. I fixed it by changing to:

add_options_page('Reaction buttons', 'Reaction Buttons', 'administrator', 'reaction_buttons', 'reaction_buttons_submenu');

..just in case anyone else runs into this or plugin author wants to edit. Thanks!
