The Elemental Shaman implementation was one of the first to be done after Shadow and has largely been left alone. There are a lot of issues with it that could use cleanup, including a bug involving Stormkeeper as a result.

Do some cleanup/refactor of Elemental and the Shaman module overall to bring it more in line with Hunters/Priests/Warriors/Demon Hunters in structure:

- [ ] Multispec support structural changes (even if Enhancement and Restoration aren't planned any time soon)

• Standardize variable names
• • E.g. "stacks" instead of "stacksRemaining"
• Poll for updates about stack counts and buff times remaining instead of manually tracking them when warranted
• • E.g. The Anima Power "Depleted Tesla Coil" (https://www.wowhead.com/spell=350248/depleted-tesla-coil) isn't being handled right.
• Legendaries
• • Echoes of Great Sundering (https://ptr.wowhead.com/spell=336215/echoes-of-great-sundering)
• • • Bar Text for time remaining
• • • Icon
• Anima Powers worth considering:
• • Depleted Tesla Coil (https://www.wowhead.com/spell=350248/depleted-tesla-coil) -- see above

Depleted Tesla Coil issue reported by Husky in Discord.

Pruning a bunch of this down. I'll do further refactors once another spec is added. Too much potential for new bugs to be introduced on what is a stable implementation.
