Additive AI Picker

- Implemented multi-crafting! Enter the sub-recipe, the number of crafting attempts, and click on "Start Craft" on the AAIP Window! You should be able to change the number of crafting attempts on the fly. You can also click on "Stop & Clear" to "reset" AAIP.

Please note that it's a first implementation, user input isn't secured (ie. there's nothing preventing you from entering something else than a number in the crafting attempts textbox...Doing so will obviously break AAIP), and specials cases must be handled (ie. no more components to make more crafting attempts). Perhaps I'll do it Soon^TM...
