Make TagComponent inherit from Component

[wingyplus]

After I read PR #114, and I understand it correctly, components in queries can accept TagComponent not just Component and NotComponent. So type def should be:

static queries: {
    [queryName: string]: {
      components: (Component | TagComponent | NotComponent)[],
      ...
    }
};

Why it's that. Because TagComponent doesn't inherited from Component. I think TagComponent should be the kind of Component that has only reset method.
