Subject: * 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
