* Minimized the number of times textures are pulled off the priority queue

* OnQueueEmpty is still called async, but will not be called for a given category if the previous callback for that category is still running. This is the most balanced behavior I could find, and seems to work well
* Added support for the old [ClientStack.LindenUDP] settings (including setting the receive buffer size) and added the new token bucket and global throttle settings
* Added the AssetLoaderEnabled config variable to optionally disable loading assets from XML every startup. This gives a dramatic improvement in startup times for those who don't need the functionality every startup

-    ; This is the multiplier applied to all client throttles for outgoing UDP network data
-    ; If it is set to 1, then we obey the throttle settings as given to us by the client.  If it is set to 3, for example, then we
-    ; multiply that setting by 3 (e.g. if the client gives us a setting of 250 kilobits per second then we
-    ; will actually push down data at a maximum rate of 750 kilobits per second).
-    ;
-    ; In principle, setting a multiplier greater than 1 will allow data to be pushed down to a client much faster
-    ; than its UI allows the setting to go.  This may be okay in some situations, such as standalone OpenSim
-    ; applications on a LAN.  However, the greater the multipler, the higher the risk of packet drop, resulting
-    ; in symptoms such as missing terrain or objects.  A much better solution is to change the client UI to allow
-    ; higher network bandwidth settings directly, though this isn't always possible.
-    ;
-    ; Currently this setting is 2 by default because we currently send much more texture data than is strictly
-    ; necessary.  A setting of 1 could result in slow texture transfer.  This will be fixed when the transfer
-    ; of textures at different levels of quality is improved.
