NoPort Dashboard overwrites the log file

Is your feature request related to a problem? Please describe.

NoPort Dashboard overwrites the log file whenever the NoPort app starts.

Describe the solution you'd like

Don't overwrite the log every time the application starts. I would like the application to allow me to select the number of days to save the log files. We can make the default 7 days and enable a user/admin person to set the number of days between 1 and 30 days.

Describe alternatives you've considered

Only overwrite the log file after the application has been started a minimum of 3 times.

Additional context

I installed the 1.1.15 NoPorts last night and the one connection I had running before the NoPorts Dashboard was replaced by Test Flight was stuck in an unusable state. I tried to get the logs from last night but they were gone.
