Cleaned up various configuration options. Removed the category throttle 

limits because the only ones used now are the defaults (which are overwritten
by the client throttles anyway). Updated the default rates to correspond to
about 350kbps.

Also added a configuration to disable adaptive throttle. The default
is the previous behavior (no adaptation).
