More sensible $WAKATIME_HOME default

[kidonng]

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

$WAKATIME_HOME defaults to your user's $HOME directory.

Convenient, right? Until you come up with the same question as many others have:

$ ls -a ~ | grep wakatime
.wakatime
.wakatime-internal.cfg
.wakatime.bdb
.wakatime.cfg
.wakatime.data
.wakatime.log

So after some digging you find $WAKATIME_HOME, which is great except it is not obvious how to set environment variable in Windows and especially macOS, which keeps the environment in some obscure location.

Describe the solution you'd like to see

$WAKATIME_HOME should have a more sensible default that doesn't clutter user's home directory, like $XDG_CONFIG_HOME/wakatime (where $XDG_CONFIG_HOME defaults to $HOME/.config if not set), or $HOME/.wakatime where the CLI is already stored.

Describe alternatives you've considered

Ask everyone to set $WAKATIME_HOME 🤷

How about we move all these files into the ~/.wakatime/ folder by default?

@nagromc Oops, then this is more likely a duplicate.

But I'd really like to see this being pushed forward instead of waiting for 5 months 😅
