* PHP:

- Converted all short PHP tags to allow phpRemoteShell to work with "short_open_tag=Off".

* File browser:

- Now it should work on some condition with PHP safe mode.

* Menus:

- Better menu management.

* Other:

- Better safe mode handling.
- Can now handle HTML output for both Shell commands and PHP code section.
- A temporary fix for utf8 decode function (it hopefully do not cause web server child segfault anymore).
