Items cleaned up

[Willowlark]

Couple of the key changes

• Pocket and Category added, Category a way to sub divide a Pocket. Pocket name comes from the games. See the full combo list of these below
• OneUse flag
• Core flag
• PMD Flag (this is rough, I just based it on if the original entry had a PMD price)
• the ForPokemon field now lists space separated _id's of pokemon. should be easier for cross checking and eliminated the commas in cells.
• Healing things split betwee HealthRestored and Cures columns for health gain and stats respectively.
• Boost & Value for one or more stats being increased by Value

(Ignore the index)

Definitely open to comments on the categories and pockets. BattleItem is anything that has a mechanic attached pretty much, generic held items (no category) are out of combat ones like Amulet coin. That said, like 80% of the battle items aren't Core so I don't super care about them (Should they be removed?)

It seems like the "Core" field is either a boolean true or an empty string "", I guess that's not intended? I don't know where some of these items come from (there are items that are neither from PMD nor the main games, so I guess they're just homebrew?), but if you want to keep the non-Core ones, I'd find it a bit cleaner to have a single source field instead of boolean flags that encodes where the item is from as a string, e.g. Core 2.0, PMD 1.1, Homebrew, ...

The HealthRestored field will be great for automation, but it should probably be a number instead of a string.
