Component Hook.

[lihaochen910]

Add component-related event handling.
(Code may need tidying up)

Thanks a lot! That looks promising ^^

Could you please update the branch to the latest master? If i saw that correctly its still using a slightly older version. And could you provide a small code sample aswell? :D

Sorry forgot to merge to latest, this is my second time using Pull Request operation. please advise. :)

An example of use is as follows:

var componentHook = new ComponentHookRecord< Transform >{
    OnAdd = ( in Entity entity, ref Transform component ) =>
    {

    },
    OnSet = ( in Entity entity, ref Transform component ) =>
    {

    }, 
    OnRemove = ( in Entity entity, ref Transform component ) =>
    {

    }
};
world.RegisterComponentHook(componentHook);

    OnAdd = ( in Entity entity, ref Transform component ) =>
    {

    },
    OnSet = ( in Entity entity, ref Transform component ) =>
    {

    }, 
    OnRemove = ( in Entity entity, ref Transform component ) =>
    {

    }
};
world.RegisterComponentHook(componentHook);

Thanks, looks great! I'll gonna test it later and then merge it :) (Once I'm home).
Could you probably add documentation later on? That would be great since i haven't written the code... and for others to understand it. Should fit the other documentations from the rest of the project ^^

[lihaochen910]

Ok, I'll submit it after I finish the documentation.

Closed in favor for #98
