Very simple addon with no configuration.

Addon adds a coundown timer to the standard blizzard castingbarframe. This is untested alongside other casting mods, as it was never intended to work with those.

This addon works with channeled spells and regular cast spells, as well as most other effects that use the standard frame.

Now added support for the "Mirror" bar, which is the bar for breath, feign death, exhaustion, etc.

Please let me know via the comments if you have any issues.
