CDelegate 调用equal的时候返回false #99

原因是:CDelegate(O* pObj, Fn pFn) : CDelegateBase(pObj, &pFn), m_pFn(pFn) { }
中的 
&pFn,对于同一个方法,取得只是指向这个方法的地址,但是�
��个地址可能每次都不一样,
这就造成每次赋值给CDelegateBase::m_pFn的值都不一样

修改方法:

CDelegate(O* pObj, Fn pFn) : CDelegateBase(pObj, ((void*)(*(int *)&(pFn)))), 
m_pFn(pFn) { }
赋值给CDelegateBase::m_pFn的值就是方法指针本身,这个就能保证
同一个方法,传进来的值都是一样的

使用uintptr_t代替int,应该更适合跨平台兼容
