Fixed /e preg_replace modifier exactly like in 0dc8b27a6a47c22a20efd7172fd71d88234869ca
Compatibility fixes

- PHP4 doesn't allow method chaining
- $_SESSION isn't always defined
- on PHP5.1 and earlier using 0x100000000 instead of 4294967296 gives E_NOTICE
- array('Net_SSH2', 'func_name') doesn't work so we fix this by passing $this to it.
  to make that work on PHP4 pass by call-time reference. normally this would result
  in a fatal error on PHP5.4+ but doesn't seem to in this case. the following URL
  elaborates:
