Added the configuration variable $conf['demo_mode'] in the config.inc.php file. It disables the newly introduced demo mode which limits certain actions in the interface part of ispconfig: the demo mode can be used to run the ispconfig interface part as online demo.

Patch from Filip that enables settting of sys_user.modules and sys_user.startmodule via client_add remote API call

Fixed: FS#1220 - /var/vmail/(domain)/(user) directories and files not delete when mail_user is deleted via remote.

Implemented: FS#1252 - Add permission system based on user / password to app installer 

BugFix: FS#1234 - CLIENTNAME value when in reseller account - fixed with suggestion from Ciaran Johnston (cj). I make initial test and this worked fine but, need check if this fix impact affect any another part of ispconfig.

- I had to reorder the variables in language_list.htm for the link URL's
- Moved the lang_file var to the beginning of the URL to make it work.
- For some strange reason if you have &lang_file in the url it changes it to <_file.

- Fixed a formatting problem with suphp.conf and newer suphp versions.
