Stock_import name BUG fixed, Issue #10:

- now it adds space char between komma and letter
- urlcreator renamed to stringmanipulator
- some comments added
- unnecessary includes removed
Stock_import Security matters:

- checking the request IP address, wheter 127.0.0.1 or other
- when IP differs 127.0.0.1 checks the POST param import_pass, to gain rights to run import
- import_pass is saved in config.php
