Crafting Bowl: Simplify implemenation

[khoidauminh]

I saw that it was checking the ingredients against recipes for presumably every tick when stirring, so I've changed the code so that it only matches once when stirred is exactly STIRS_NEEDED. stirred will go above STIRS_NEEDED by 1 value if a recipe match is found, so now only values greater than STIRS_NEEDED will change the bowl sprite to full.

Some more small changes:

• Any interaction on a finished bowl will always pop out its items. This is so that you dont accidentally add an item into a finished bowl.
• Adding items to the bowl resets its STIRRED property. This completes the recipe fix above.
• Remainder items stay in the bowl and is popped out with the result item.
• You can stirr a full bowl even with an item on the hand, for personal convenience :]
