Add filter to change expiration dates on the membership card

[andrewlimaza]

• ENHANCEMENT: Added filter 'pmpro_membership_card_member_end_date' to allow developers to adjust the output of the expiration date for the membership card. It takes the $date and $pmpro_membership_card_user respectively.

Note: This also improves the sanitization on the output to use escape functions.

Now that it is in core, I wonder if we can use the function pmpro_get_membership_expiration_text in this Add On?
