Allow ".stackwallet" directory to meet XDG Base Directory spec

[et-rnal]

Is there an existing issue for this?

• [X] I have searched the existing issues

Current Behavior

Currently on Linux, running stack wallet produces a "$HOME/.stackwallet" directory.

Expected Behavior

I suggest adding the ability to configure where this directory goes so that we may have it placed in "$XDG_CONFIG_HOME" (~/.config) or "XDG_DATA_HOME" (~/.local/share)

This could be accomplished by having it use one of those variables by default, checking if they're present, or allowing the user to configure it.

Reproduce Steps

Run stack wallet.

Environment

Any GNU/Linux environment
