updateSettingsFile

Update the Settings.php file. The most important function in this file for mod makers happens to be the updateSettingsFile() function, but it shouldn't be used often anyway. - updates the Settings.php file with the changes supplied in config_vars. - expects config_vars to be an associative array, with the keys as the variable names in Settings.php, and the values the variable values. - does not escape or quote values. - preserves case, formatting, and additional options in file. - writes nothing if the resulting file would be less than 10 lines in length (sanity check for read lock.) - check for changes to db_last_error and passes those off to a separate handler - attempts to create a backup file and will use it should the writing of the new settings file fail
