Allow another ledger file for settings/setup

[Anachron]

My use-case: Right now I have a single ledger.daton my phone that I sync via syncthing between my phone and my computer (where all my other ledger files are). I read this ledger file and compare it with my other ledger.dat files on the computer and see which entries have been added.

Right now cone only supports one file, which means I have my accounts at the top of the file and the entries after. This become a bit of work whenever I edit my accounts file on the laptop because I can't just sync it back to cone, I have to manually modify the file for the phone as well.

If cone were to support another file to open and use as a set up, it would help me quite a bit to make it a bit less painful to sync my accounts back from the computer to the phone.

@Anachron Hello, thank you for the issue.

Oh! I just realized the similar issue is yours https://github.com/bradyt/cone/issues/26.

Is this an exact duplicate issue, or were you asking for something slightly different here?

This issue is slightly different, I was thinking for a second ledger file (not includes) which I can use for accounts only.
