* Implemented and tested the OnBalanceUpdated event * Created a SendInitialPackets() function and commented our current knowledge of the login packets * CurrentRegion.Handle is now set at login * Moved the README.Mono file to README.txt and added a bit more information * Fixed the sldump example to use the 1,50,50,50 version number * Generated an updated _Packets_.cs file git-svn-id: http://libopenmetaverse.googlecode.com/svn/trunk@319 52acb1d6-8a22-11de-b505-999d5b087335
