[Suggestion] Jewels/cluster jewels included in Gear set + autoswitch for passive tree

Hey there,
first i must praise your work on POB. Can't life without it.

I'd like to see these functions added if possible (more and more build guides only exist in POB nowadays)

1. make jewels sockets be able to saved with gear template or make a separate template for it cause its a pain to switch out all the jewels when you transit to other stages of a build (e.g. no cluster -> cluster)
   I thing a separate present would be more flexible than saving it with the gear set

2. if possible make gear/jewel presents be able to be linked to a passive tree present for easy switching between stages from a build like life based->es->ll

3. make the configs be savable to the different tree presents cause the settings might quite differ like non crit -> crit or depending on stuff that's specific to gear / skill combos (e.g. Flesh and Stone + maim in sand stance) that isn't auto detected by POB already

4. make the char import be able to utilize 1.-3.

No files, tests, or entry points are named. Start by tracing how gear, jewel, passive-tree, and configuration presets are represented, then define the scope of linking them and supporting character import. Done should cover the requested preset switching and saved configurations without losing the relevant build state.
