HASH_FIND_INT —> HASH_FIND_PTR for CCAcitonManager.cpp and CCScheduler.cpp.
Using std::unordered_map instead of UTHASH for js_type_class_t.
Since xxx.hash_code() return size_t which is 8bytes on 64bit system, we should not use HASH_ADD_INT and HASH_FIND_INT for js_type_class_t.
Updating Bindings-generator.
