Various improvements
- Support for leave event, via DOTENV_FILE_LEAVE and _dotenv_event (can use DOTENV_FILE_LEAVE=$DOTENV_FILE_ENTER). - Support for searching upwards for $DOTENV_FILE_ENTER (#3). - Source .env only once per session, but re-source when leave events are enabled (#1). - Trigger the machinery when the script gets sourced, for the current dir (#2).
