* Fixed SecondLife.GetAgentDetails to prevent it from registering multiple callbacks

Browse Source 
* Added code documentation skeletons in SecondLife.cs
* Removed Helpers.Log and replaced it with SecondLife.Log that is silent if SecondLife.Debug = false;
* Removed logging from ProtocolManager.cs where an exception was also being thrown
* Replaced logging in the FieldToString method with a sensible return value on error
* Replaced Packet.Blocks() logging with an ugly hack for now
* Replaced most logging with exception throwing to prevent broken apps from breaking further
* Formatting fixes for some of the files
