Feature Request: Move .aider* files into an .aider directory

[ziemkowski]

Issue

It would be nice if there were fewer top-level files/directories while using Aider. Would you consider moving the files Aider uses into a directory? For example...

.aider/
    chat.history.md
    conf.yml
    ignore.txt
    input.history
    tags.cache.v3

I imagine you'd still want to support looking for both .aider.conf.yml and .aider/conf.yml automatically though.

In part you can do this yet, compare #2325.

Also would be good if name is configurable for .aider folder, or location
