Restore lag comp quota behavior

Lag comp quota is intended to build up each turn so that it can be used
for spikes.  The current code depletes quota on slow computers, and
even for computers with cpu lag below .04s, quota builds too slowly to
be able to be used for multiple spikes in a game.

This patch is intended to be a short term fix, with a significant
code and documentation overhaul planned in the near future.
