Link to another entry (or alias entry)

[bluerv]

There are many instances where an account on one site is actually managed by another account. For example, a dndbeyond login might be through google, twitch, or apple, but which one is it? Adding an entry for it makes sense, but there's no password and you have to add a field that says "go look here".

What would be better is if there were a way to mark those as an Alias or a "hyperlink" or something similar so that it's obvious that the login is actually through another entry.

This is related to #223, but is also slightly different. I like this idea, but I feel that it needs to be fleshed out a little more. What does the link determine? Just login assistance? Ie. when searching for an entry to login with, and EntryB is found, if it links to EntryA there'd be some way to just enter EntryA's details?

I'll move this to the core libary as that's where it belongs.. but this still needs a little work.
