pkgs/vim: Add plugin for Ledger

The plugin really is for Ledger instead of hledger, but both should be
compatible with the syntax. If we use something that's not compatible we
can still patch it in.

I also set the default currency to Euro and added an auto-align after
leaving insert mode because I'm lazy ;-)
