WCFM Support in Free version

1) Clicking on Store link in dropdown searchbox leads to Vendor list instead of the vendor page. So, I looked up the code and found this:
$store_url = $WCFMmp->wcfmmp_store->get_shop_url();
instead of
$store_url = wcfmmp_get_store_url( $vendor_id );
for it to work

2) It would be nice to change placeholder text in search box when switching to WCFM vendor page because the Search is limited to vendor items. The custom placeholder text will look funny on the vendor page.

3) In a WCFM setup with AWS, data does not seem to automatically update the search index table. I modified the code in product_changed function before things work as expected:

    if ( wp_is_post_revision( $post_id ) ) {
        $this->update_table( $post_id );
        return;
    }

Overall, this search plugin best suit for WCFM.
