Item name group refactor & /received filtering rework

[Salzkorn]

What is this fixing or adding?

This expands existing item name groups and changes how filtering works for the /received command.

Item name groups now live in their own file, and a lot of automation for them has been added.

• All previously existing groups still exist
• Groups based on item flag groups are unified
  • This means "Unit" contains items from the "Unit" and "Unit 2" groups, "Armory" contains "Armory 1-6", etc.
• Item races are groups, including "Any"
• Items with brackets get alias groups, so eg. "Advanced Healing AI" can be used instead of "Advanced Healing AI (Medivac)"
  • This existed previously, but only for a hand-picked subset of item flag groups
  • It now checks all item names directly
  • An exception to this are items that would be ambiguous without the bracketed part (eg. "Resource Efficiency")
• Items with parents get a single group (eg. "Zergling Items" for items with parent "Zergling")
  • The special name is used to avoid ambiguity with the parent item in YAMLs
  • This does not currently respect items with multiple potential parents

The /received command can now take a partial item name or a full group name as a filter.
This does not currently have simplified inputs for items or groups with punctuation, eg. "WILD" will not match "W.I.L.D. Missiles (Viking)", "TalDarim" will not match "Tal'Darim".

There is also not currently a user-facing way to see all possible groups. There is some ground work for filtering developer-facing groups and "obvious" groups (the bracket alias & child item groups, specifically), but this is not currently applied anywhere.

How was this tested?

Messing around with the command in the beta async.

If this makes graphical changes, please attach screenshots.
