dbscripts fail when DB settings are without password

it took me some minutes to find out dbscripts was giving me "Improper database connection settings." because of the regexp using to parse the connection assumes one is using a password (a good practice indeed, but its a @local environment), so here is a quick and dirty fix :P

dbscripts.modules line 1759

[code]

function _dbscripts_db_connect() {
require('config.inc');
require("$settings_path");

// Ensure required files are loaded
if (!isset($dump_path)) return "The file 'config.inc' does not exist. Copy from the example version?";
if (!isset($db_url)) return "The file 'settings.php' file does not exist.";

preg_match('/'.$dbtype.':\/\/([^:]+):([^@]+)@([^\/]+)\/(.+)/', $db_url, $db_settings);

if(empty($db_settings)) {

//try to parse without password
preg_match('/'.$dbtype.':\/\/([^:]+)@([^\/]+)\/(.+)/', $db_url, $db_settings);

if(!empty($db_settings)){

//match index are different
//so we cannot reuse code
$dbuser = $db_settings[1];
$dbhost = $db_settings[2];
$dbname = $db_settings[3];

//plus we need to return a different string
return "-u $dbuser -h $dbhost $dbname";

}else{
return false;
}

}else{

$dbuser = $db_settings[1];
$dbpassword = $db_settings[2];
$dbhost = $db_settings[3];
$dbname = $db_settings[4];

return "-u $dbuser -p$dbpassword -h $dbhost $dbname";

}

}
