New client features and fixes

[EnPassant4264]

Item features (will be proposing these to main):

• Ratings: Mods can define whether an item is Popular, regular, usually useless, useless, or Pokemon-specific
  -- All custom Mega Stones and items with an itemUser defined default to Pokemon-specific like the real items do
  -- (minor) Booster Energy is now classified as specific to Paradox Pokemon
• Individual mod isNonstandard changes now display in teambuilder

Move useful/useless:

• The short and easy way: Adding viable: true/false to a move will force it to be one or the other. If not present, it defaults to the usual algorithm.
• The long and thorough way: Mods can now add their own version of the moveIsNotUseless function (and the four tables it uses, if desired) to their teambuilderConfig. After the normal function is run, the mod's version will be, and it will override only if it returns a value for that move.

Fixes:

• Sketch properly includes a mod's new and removed moves and can follow the same usefulness features
• Script-altered Uber additions now reflect the bans on alternate formes in Pokemon selection
• Gen 1 tradebacks correctly appear when searching Pokemon by move.

I tested the hell out of this in mods of as many types as should be affected (ones with Megas, National Dex mods, past gen mods, Gen 2 Doubles since it acts uniquely, and of course Earth & Sky since it makes changes for everything under the sun), including after transferring and pushing the changes on the DH side.

if I can ever find time I will test all of this locally as well. But at a glance this looks fine to me
