no call file.clean() changing package view - it makes no sense because we are going to request a new datestamp file. moreover file.clean() and file.get() in chain cause page flickering

this interface.

Update README e config.js according with.

ok ... config.user has more problems than I expected - removed at least for now capability to select a uid - still checking if node has been launched with sudo and go down permission to original user id

better socket io configuration - DO NOT USE config.debug, it makes conflicts with other internal functions

moved required libs back on top - moved setuid after setgid (if you set uid before, you will not be able to switch group after just because you have lost permissions)
