Arbitrary data search within packfiles

[ShadelessFox]

It's quite hard to find useful bits of information by blindly inspecting each core file one at a time.

It will be a lot faster to scan the entire packfile for a given sequence of bytes, words, dwords, and etc and then show core entries that contain these.

Maybe add a simple middleground by displaying the Id field on the items's "header", if present?

Something like this.

This is a good point. The main issue is that not every type has a field called "Id". Some types might have meaning identifiers, whereas others don't. Unfortunately, there are no dedicated types (such as Resource in HZD or ResourceWithName in DS) that guarantee these fields exist.
