Add cache rebuild process to wp_cron

[ocReaper]

It's insane to rebuild the cache manually. The computers get together at night and laugh on us!
I had to add this tiny little code to my theme to do it, but you should add the cron to the plugins activation hook.

function rebuildShop() {
    Bigcommerce_parser::BuildCategoriesSelect(true);
    Bigcommerce_parser::BuildProductsSelect(true);
}
if( !wp_next_scheduled( 'rebuildShop' ) ) {
    wp_schedule_event(time(), 'daily', 'rebuildShop');
}
