FileManager.Request: assume 'filemanager' parameter is always set --> removed the checks.

list_row_maker: don't let it clutter global space, but tack it onto FileManager itself.

requests: always bind the onComplete(), etc. functions to 'this' (== FileManager instance): unified coding throughout FileManager

FileManager.Request: options.data should ALWAYS have precedence over propagateData! In the usual circumstances, this does not matter at all, but when anyone sets properties in propagateData which clash with the ones in options.data, then correct operation is ONLY guaranteed when options.data can overrule such collisions.
