Add data directory excluding sessions to dump (#586)

[mkuhlmann]

This includes the data directory inside a gitea dump. Sessions are excluded if the session provider is set to file and the session directory is a child of the data directory.

Closes #586

sessions dir is still in the data

[mkuhlmann]

Works now. The issue was an unset PROVIDER_CONFIG in custom app.ini. Then the configuration value is just empty and macaron uses a standard data/sessions. Thats another bug that should be resolved, since the expected behavior should session path to be relative to APP_DATA_PATH and not to the executable path. If APP_DATA_PATH is set to another location but PROVIDER_CONFIG is not set, sessions will be still saved to data/sessions.

I've hardcoded data/sessions to match macarons fallback config var as a workaround and it works for now.

Please don't use uncommon abbreviations for variables :)

[bkcsoft]

[bkcsoft]
