End-of-turn + Ability persistence fixes

[theastrogoth]

closes #220

Tweaks things to use the end of 4-move "turns" for a lot of item/ability effects. Some of these might still need in-game confirmation:

• Everything handled by the getEndOfTurn method
  • brn/psn damage
  • Grassy Terrain healing
  • Ingrain
  • Leftovers
  • Rain Dish / Dry Skin / Solar Power
• Toxic/Flame Orb (confirmed for raiders)
• Hydration (needs testing)
• Harvest
• Cud Chew
• Speed Boost (only after a non-cheer move is done first)

These changes broke a couple of published strats:

• Woodland Magic Show for Venusaur (Meowscarada is damaged by PSN an additional time compared to before, causing it to faint)
• Inconspicuous Chandelier for Meganium (the boss takes way less PSN damage, since it is happening 1/4 as often now)

Things that aren't changed yet that still could use some testing:

• Yawn
• Syrup Bomb
• Field Effects wearing off
  • Screens
  • Terrain/Weather
  • Cheers

Some things are handled differently for bosses compared to raiders (e.g. Speed Boost).

A few other things were added to this, mostly because I was too lazy to handle them in separate commits or a different PR:

• Added hitsTaken and timesFainted to the HP Display Popover when they're relevant (when Rage Fist or Last Respects/Supreme Overlord are present, respectively)
• Added "Effective Speed" to the popover as well (when speed is modified due to stat stages, paralysis, etc)
• Fixed the healing on Ingrain when a Big Root is held.
• Added Smack Down as a condition that imbues Grounded
• Make Status moves unselectable when holding an Assault Vest
• Added Speed Swap and fixed Power Trick
• Cleaned up things to get rid of linter warnings

Not sure if these points have been tested or not by now: I believe Syrup Bomb, Screens, Weather (presumably Terrain), and Cheers are all turn-based. The "turns remaining" counter in the menu can skip if you don't move and teammates advance the turn.

For the failing Espathra test case, I remember when running it, Espathra would sometimes have +3 speed at the end and sometimes +4.
