Add option for keeping log filesdisplay-config-errors

Since it's not unusual to spawn a lot of different terminal emulators
without restarting, Alacritty can create a ton of different log files.

To combat this problem, logfiles are now removed by default after
Alacritty has been closed. If the user wants to persist the log of a
single session, the `--persistent_logging` option can be used. For
persisting all log files, the `persistent_logging` option can be set in
the configuration file
