How do I know where the config file is present, without looking into the code

To maintain some state, akcess manages a config file that gets created either in $HOME/.akcess/config or /tmp/.akcess/config based on wheter $HOME is set of not. We should have a way to tell users where the file was created. Some of the things that should be considered while implementing are

• There are chances that initially the $HOME env var was not set, but has been set now
• If the config file is present at both location, what should be done

I think we should output where the config file is present as output of version command.

akcess version
0.0.4
