[sldev] Uncouple Avatar movement from Sim

[alexander treptow]

I know that there is no physics calculation and no collision detection 
in the client, but i want to have an avatarviewer that only shows the 
avatar and makes it possible to save the animated avatar to a .gif or 
so. For example in a 100x100 Pixel Size to have your avatar animated as 
forumavatar in every kind of forum.

I know that all the calls from the server for object movement are 
handled in the processUpdateMessage method but i dont know what globals 
are modified or what functions for avatar movement this function calls. 
I'll try to figure it out today.

If it works how i want to i ll have to write my own scanKeyboad function 
that handles the internal control flags and set the right states. so 
that the avatar moves without any server communication.
