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)

we do not really need to wait window.on('load') event because scripts are located on the pottom of layout.ejs, so when they run html is already loaded - removed
