Added functionality for Apple Wallet.

[andrewlimaza]

• ENHANCEMENT: Added the ability to show Add to Wallet for Apple devices and create a generic pass for these devices. To show this on your membership card page use the attribute show_wallet_btn="true" and it will automatically appear for relevant devices. This automatically shows a QR code when scanned will return text information about the members level. This is somewhat limited to Multiple Memberships Per User and for simplicity only one level is shown on the wallet's pass (as space is very limited).

  • The pass assets and values can be tweaked by using the following filters respectively: pmpro_membership_card_apple_wallet_args and pmpro_membership_card_apple_wallet_assets.

• ENHANCEMENT: Added a new shortcode to show the Add to Wallet button anywhere on your site for members. [pmpro_membership_card_show_wallet].

Example of the pass:

TODO:

We need to obtain our own Apple Developer certificate and load it to a server and link to it.
