+ setup_demo gives errors under postgres
+ setup_demo can save special chars in the admin name
- renamed setup_demo into admin_account, as setting up demo accounts is the least used function of it
- fixed warning db::delete missing params, if delete_all was checked
It's a bit obscure:
$deletedomain='';
$domain='default';
isset($deletedomain[$domain]) === true
under linux this is NOT true
fixed it by using: is_array($deletedomain) && isset($deletedomain[$domain])
2) $GLOBALS['phpgw{_info}'] ==> $GLOBALS['egw{_info}']
3) moved setup-classes from phpgwapi/inc back to setup/inc (they are not used anywhere else, but in setup)
