smarty.inc.php: interface cleanup etc.

- move initialisation of $smarty->template_dir, compile_dir and 
  config_dir into __construct() of PFASmarty class
- remove usage of /tmp/postfixadmin_templates_c/ to avoid security
  risks (symlink attacks etc.)
- remove __set, __get and __call from PFASmarty class to ensure we
  have a clearly documented interface to the template layer
- whitespace changes (mostly in select_options())
- added vim: line

See also the discussion about the r949 commit in postfixadmin-devel
for details.
