Played with BasicItemFactory:

Played with BasicItemFactory:
 * added a virtual destructor (good for abstract classes :))
 * added a method for creating an item using factory name and item's id
 * hid createItem method (as I want it to be used from within BasicItemFactory::create method only)
 * addedd deRegisterFactory method (I'm not sure if it's really needed or how to properly implement it ;(
 * added 'static' to ourFactories definition (fixed a problem)
