Spying, jumpers, revenge

Hi, got a few suggestions:

1. Need some kind of clan history on members trying to join our clan.

2. Need a ban function, so that jumpers won't get in again.

3. Need a checkbox for disabling each member from cw, kicking and inviting is just stupid - but needed right now.

4. Would be nice if it was possible to "next" through the list of revenge opportunities.

5. Would be cool if we could see the "run-out-time" of active shields when trying to revenge somebody.
