User data locations

Yrendr uses the standard Windows application-data locations rather than one hard-coded home directory.

Windows

Preferences use %APPDATA%\Yrendr. Persistent data uses %LOCALAPPDATA%\Yrendr, with cache data under %LOCALAPPDATA%\Yrendr\Cache.

Override

Set YRENDR_USER_DATA_DIR to force one explicit root. This is useful for portable development and clean test environments.
