PW WooCommerce Gift Cards Pro 3.1

- For physical gift cards, do not show the Generated And Emailed After Complete message to the customer since this could be confusing.

- Fixed a conflict with WooCommerce Multilingual that occurs when changing the shipping method on the Cart or Checkout pages. Added new hooks that can be used to alter the values displayed in the gift card email template without having to override the template: pwgc_email_template_to_label, pwgc_email_template_to, pwgc_email_template_from_label, pwgc_email_template_from, pwgc_email_template_message, pwgc_email_template_title, pwgc_email_template_amount_label, pwgc_email_template_amount, pwgc_email_template_number_label, pwgc_email_template_number, pwgc_email_template_expiration_date_label, pwgc_email_template_expiration_date, pwgc_email_template_redeem_url, pwgc_email_template_redeem_button_text, pwgc_email_template_view_email_url, pwgc_email_template_pdf_link_text.

- Prevent the Email Design meta value showing for Physical Gift Cards.
