For Evoker: Track the current empower level of the spell

[Betaskill]

Is your feature request related to a problem? Please describe.
No

Describe the solution you'd like

First of all thanks for the great addon and the time that is used for making it happen.

I would like to have a condition (or icon) where you can track the current empower level of the spell that is casting, with: make the icon visible if you are, like, at level 2 of the spell.
So with the new class Evoker, like for example, the ppl are able to see it via a dogtag like "stacks" at which level their spell is at the moment or whatever they wanna use that information for.

Describe alternatives you've considered
No that I can think of.

Is something like this possible?

Blizzard... please...

Turns out UnitChannelInfo() returns nil when in the final stage of an empowered cast. I.. just... what...? So @arieh my clean solution doesn't work...
