v0.9.15

Added

• Added singlePersonBooking.php to handle when the participant is customer, contact and participant.
• Added __bookSingleParticipant.php and __bookMultipleParticipants.php to handle different settings.
• Fixing frontend.js to work with single participant-settings.
• Switched to openssl_encrypt/decrypt since mcrypt is deprecated
• Added class name to dates, so you can style them yourself
• Added span around venue name, so you can style it, if you want to
• Adding support to load existing attribute data to customer and contact, when loading the booking form. (Would be bad if we emptied it..)

Removed

• getallheaders is now gone, forever.
