oscar: LINE機器人傳sticker貼圖

這一篇介紹如何讓LINE機器人辦識使用者傳來的sticker，並回傳sticker給使用者。

stickers可以讓對話更有趣、更生動。

---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

以下是PHP程式碼，先將所有會用到的sticker列出來，然後判斷LINE傳來的資料型態是否為sticker，然後再隨機挑一個一開始列出來的sticker，回傳給使用者。
