What does the provided patch do?
Updated constants.lua to be current as at 5.4.7 (18019)
Please provide any additional information below.
Here is an updated constants.lua with all the current MoP cooldowns, and tidying of format (I am a little OCD).
Please don't read this as any reflection on the original authors, I love their work and that is why I have taken the time to keep this current for myself.
Hope this helps people.
