require init-pro file in pro context
separate free and pro builds
remove the patches/ folder on build
setup the pro build in a parent folder
add TC_init_pro class in inc/init-pro.php. Not part of the free version
instanciates only for the following classes 'TC_activation_key' && 'TC_theme_check_updates'
remove the ftp_push skin task on prod build (too long and useless)
add the footer-customizer as an addon in init-pro
