Implement AA timers reset on death

This is a field in the packet, live only uses this for Lay on Hands

Currently I didn't add this to the packet since it has 0 effect on the
client.

We could move this field to aa_ranks which would give more flexibility
for custom servers, but no one said they wanted it there.
