[DGD] Kotaka v0.15

[Raymond Jennings]

Got some more work done on kotaka.

* Keep account state in real time with forced saves and loads

I figure player and staff accounts should be tracked OOCly, and not be
reverted if a rollback is required.

* Prevent string overflow in log daemon by using logbufs

Really, I should have done this earlier

* Add incremental option to statedump command
* Prevent log snarling if errors happen in logging
* Make Test subsystem privileged so that it can shut the mud down on a
fatal corruption.
* Move ustates to lwo

This is one of the major overhauls.  This prevents object leakage if a user
object has to force destruct.

Included in this overhaul is moving ustate callout handling to the user
object, because ya know, you can't call_out from an lwo.

* Fix a latent double-callout bug in animation

This got sniffed out during the previous overhaul

* Don't destroy an object with outstanding instances.

Same thing skotos does
