Add blizz aura timer scaling option

[Rdyx]

Hello, I wanted to be able to scale the aura timer from blizzard to lower it because the base is taking the whole aura frame, making the aura icon barely visible.

I'm pretty noob about wow addons so sorry I'm not sure how localization works (I simply edited the enUS locally to fix the error), same for the reload triggering (simply added a tip in the option tooltip)

I'm using it locally and it works as intended, so I felt like it would be cool to make it available for some other people :)

It is hidden if Advanced is not ticked & disabled if cooldowns are not shown Have fun!
