egroupware/etemplate/inc/class.etemplate.inc.php
Ralf Becker 486a32e86d Refractured eTemplate to use: 
- the etemplate_request object which stores the request data in the
  a) session (as before) or
  b) compressed and encrypted in the form transmitted to the user
  Benefit of b) is that the session does not grow and the form can
  be submitted as long as the session exists, as we need no garbadge
  collection. Of cause more data needs to be submitt between
  browser and webserver. b) is choosen automatic if mcrypt and
  gzcompress are available, but can be turned off via setting
  etemplate_request::$request_class = 'etemplate_request_session';
- static class variables instead of the before used global ones
--> This new version of eTemplate is fully backward compatible with 1.6!
